Where the Strangeness Lives

Alice in Chains harmonises, Soundgarden reframes the meter, Pearl Jam answers. Six crossings between three bands from one city that share almost no technique.

1. ABOVE

Alice in Chains ▸ Pearl Jam — This merge has a finished album as its precedent, and almost nobody remembers it.

The variable that moves: The improvised lead moves into the written song — and lands in the one slot Cantrell writes out note for note.

Hinge (what already agrees): Mad Season. In 1994 Mike McCready met bassist John Baker Saunders in rehab in Minnesota, recruited Barrett Martin of Screaming Trees, and then went after Layne Staley — pitching it as "You do what you want, you write all the songs and the lyrics, you're the singer... I was under the mistaken theory I could help him out. I wanted to lead by example." One album, Above (1995), #24, gold, with Mark Lanegan guesting. This is the only merge in nine guides whose precedent is a complete studio album by exactly the two people involved.

Friction (what fights): Alice in Chains' leads are written; Pearl Jam's are found. Cantrell: "I'm actually much more of a writer than I am a free-form-solo kind of guy... I throw a ton of shit up against the wall, and then I pick out the best pieces and string them together," and a solo should be "a cross between a horn line and a vocal line." McCready, per Gossard, "has a tendency to float more above the track." Drop a floating pentatonic improviser into an arrangement whose lead parts are composed, doubled and harmonised, and the two leads fight — one is locked to the vocal contour and the other is deliberately not locked to anything.

Resolution: Give the band two kinds of lead and never let them overlap. The composed lead is Cantrell's: written out, phrased like a vocal, harmonised by a second guitar in parallel, and locked to the two-voice vocal melody. The found lead is McCready's: a single unaccompanied improvised pass, different every take, entering after the last chorus and running out past the end of the song. So the track has a written melody in the middle and an improvised one at the end, and the contrast between them is the arrangement. That is essentially what Above sounds like, and it's the one recipe here I can point at a record for.

2. A MELODY WITH TWO NOTES IN IT

Pearl Jam ▸ Alice in Chains — Pearl Jam's method needs the singer to arrive last. Alice in Chains' harmony has to be there from the start.

The variable that moves: The harmony moves into the process — and has to be written before the singer exists.

Hinge (what already agrees): Both bands build the music first and apply the voice afterwards. Cantrell's stated order is "music first." Pearl Jam's is the same only more extreme — Gossard, Ament and McCready cut twelve instrumentals in August 1990 with no vocal and no guide melody, and a singer they hadn't met wrote to them from San Diego. Neither band writes a tune and then arranges around it.

Friction (what fights): But a two-voice harmony can't be applied after the fact. Pearl Jam's process produces one baritone answering finished architecture. Alice in Chains' sound requires two lines interlocked — and, crucially, those lines were designed in advance and then tracked separately, because the two singers often weren't present for each other's takes. So the harmony isn't a blend that emerges in a room. It's a written object. And you cannot hand a finished instrumental to a stranger and expect a parallel-fourth two-part melody to come back.

Resolution: Write the harmony as the melody, then hand the whole thing over. Build the vocal line as a two-note object from the start — not a lead with a harmony above it, but a single melodic idea that happens to contain two pitches a fourth apart, put down as a guide before anyone sings words. Then apply the Pearl Jam process to that: give it to a singer who has never heard it, with no discussion, and let them write the words and the phrasing to the existing contour. And because both bands track separately anyway, the "the singer was never in the room" constraint isn't a compromise — it's how Alice in Chains actually made records.

3. THE VOCAL IS STILL IN FOUR

Soundgarden ▸ Alice in Chains — Cornell already solved this with one voice. Nobody has tried it with two.

The variable that moves: The harmony moves into the frame — and has to survive a bar that keeps changing length.

Hinge (what already agrees): One band taught the other its tuning, in one sentence. Cantrell asked Thayil at a Seattle club how Soundgarden got their low end; Thayil said "There's this thing called drop D tuning." Thayil on the result: "Their first demo owed a little more to Poison than the huge monster they became. That really changed when they heard us." They also share a track — Cornell sings on "Right Turn" from Sap, billed as "Alice Mudgarden" — and Cantrell played Soundgarden's 2025 Rock Hall induction, having named Thayil the best guitarist in the scene.

Friction (what fights): A parallel two-voice harmony needs a cycle the singers can feel, and Soundgarden don't reliably have one. 7/4, 5/4, 6/4, 15/8, a 19-beat cycle — and by Thayil's own account the band often didn't know: "We weren't even aware that we were doing that," and "Sometimes we'd only figure out later that a song was in 5/4 because someone tried to count it out at a gig." Two singers holding a fourth across a bar that keeps changing length will drift apart, and the whole point of the interval is that it lands exactly.

Resolution: Steal Cornell's own solution and give it a second voice. On "By Crooked Steps" he did this: "The vocal melody is still in 4/4 while the guitars are in 5… something." So put the riff in 7/4 in an open tuning, and put the two-part vocal in 4/4 over the top. The harmony stays square and internally locked; the riff underneath arrives a beat early every cycle; and the two phase against each other, landing in a different place each time until they resolve together every four bars. Soundgarden did that with one voice. Alice in Chains do the harmony over a stable four. Nobody has put a parallel-fourth two-voice melody in four over a riff in seven — and the fourth is essential here, because a third would need the chord underneath to hold still, and it won't.

4. SYMPATHETIC NOTES

Alice in Chains ▸ Soundgarden — One band tunes down a half step and stays there. The other plays whatever guitar was on the wall.

The variable that moves: The found tuning moves into the house tuning — and the architecture gets built on top of whatever you land on.

Hinge (what already agrees): Both use tuning as a compositional device, and the debt runs from Soundgarden to Alice in Chains. Thayil's drop-D sentence is why Alice in Chains stopped sounding like their first demo. And both bands have an accidental-tuning story: Alice in Chains' self-titled album has three songs — "Shame in You," "Nothin' Song," "Over Now" — in a tuning Cantrell found because a friend returned a borrowed guitar retuned. "I'm not even sure what it is, man."

Friction (what fights): But one is a house standard and the other is a scatter. Alice in Chains tune everything to E-flat and stay there; the tuning is infrastructure. Soundgarden have drop D, drop B, all-six-strings-to-E, EEBBBB, CGCGGe, DGDGBe, CFCGBe, DGDGBC and CGDGBe — a different tuning per song, arrived at opportunistically. Cornell: "It's a little bit more about proximity to the tuning as opposed to picking up a guitar, putting it into a weird tuning and then trying to create something out of it." And that has a real mechanical consequence: Cantrell's harmonised guitar lines need repeatable shapes, and a per-song invented tuning destroys shape repeatability.

Resolution: Let the tuning be found and build the architecture on it afterwards. Pick one tuning from the CGCGGe family — Thayil says it gives "a very distinct Eastern vibe" and a lot of "sympathetic notes" — and write the riff on it by feel, without working out what the chords are. Then apply the Alice in Chains method to what you found: harmonise the riff with a second guitar, mirror that same interval in the two vocals, and record the whole thing with one rhythm guitar left, one right, one lead up the middle. So the discovery is Soundgarden's and the architecture is Cantrell's. The single rule: do not retune to make the harmony easier. Find the harmony inside the tuning you landed on.

5. THE MUSICAL DIRECTOR AND THE RHYTHM SECTION

Pearl Jam ▸ Soundgarden — One man played in both bands for twenty-seven years and told us exactly what the difference was.

The variable that moves: The frame moves into the process — and lands in the drum kit only.

Hinge (what already agrees): The strongest hinge in nine guides, because the experiment was already run by one person for decades. Matt Cameron drummed for Soundgarden from 1986 and for Pearl Jam from 1998 — simultaneously from 2010 to 2017. And he described the difference himself: "my role in Soundgarden is a little bit more of a musical director role, whereas in Pearl Jam it's more of a supporting-in-the-rhythm-section kind of role." Before either, he played on Temple of the Dog in 1990 alongside Cornell, Gossard, Ament, McCready and Vedder — five of the six people in this merge, in one room.

Friction (what fights): And his own testimony is the friction. In Soundgarden he was the one who worked out what the meters were — Thayil: "The task of figuring out the time signatures for Soundgarden's songs was usually left to Cameron." Joining Pearl Jam, the first thing he had to do was subtract: "I was playing way too fast. I had to chill out." So the same drummer had to switch off the exact capability that made him indispensable in the other band. And Pearl Jam are, as far as any documented source shows, a standard-tuning 4/4 band — the only claims otherwise live on fan forums.

Resolution: Put the odd meter in the drums and leave literally everything else in four. Guitars in standard tuning playing a straight 4/4 verse-chorus rock song, vocal in four, bass in four — and a drum pattern underneath in 7/4 or 5/4 that only resolves with the bar every few cycles. That inverts Cornell's own trick: on "By Crooked Steps" the guitars were in five and the voice in four; here the drums are in seven and everything else is in four. Cameron's own instruction for how to feel it is the recipe: "I try to inhabit the five as 4/4 there... I count that as 1-2, 1-2-3." It's the only merge in this guide where the drummer is the strange element and the song is otherwise entirely conventional — which is precisely what a musical director stuck in a rhythm-section chair would actually sound like.

6. ONE MICROPHONE

Soundgarden ▸ Pearl Jam — It happened once, by accident, at one microphone, and produced the best-known song either band was involved in.

The variable that moves: The process moves into the frame — and requires manufacturing a gap that doesn't exist.

Hinge (what already agrees): "Hunger Strike." Cornell was stuck restructuring a song with only one verse when Vedder — newly arrived from San Diego, in the room to audition for a different band — walked up uninvited and sang the low part. Cornell: "I feel this shadow presence over my shoulder. And there's only one mike... So he hit the 'Going hungry,' I sang the high part and then he hit it again. All of a sudden, a lightbulb went off in my head and I thought, 'Fuck, his voice sounds incredible in that deep register.'" Vedder: "I could hear what he was trying to do, so I walked up to the mic — which I'm really surprised I did." That is Pearl Jam's process — a singer answering someone else's finished music — happening inside a Soundgarden song, and it worked immediately.

Friction (what fights): But Soundgarden have no gap to answer into. Cornell wrote the music, the tuning, the meter and the vocal, usually alone. Thayil on "Black Hole Sun": "Chris wrote that thing from top to bottom." Pearl Jam's method structurally depends on separation — one party builds, a different party receives it cold and responds. In Soundgarden the builder and the voice are the same person, which means there is nothing for a second singer to answer.

Resolution: Manufacture the gap on purpose. Write the whole thing Soundgarden-style — one person, one found tuning, one odd meter, no vocal and no guide melody at all — then hand it to a completely different singer with a lower voice who has never heard it and no context for it. And place the two voices exactly where "Hunger Strike" placed them: the high voice takes the exposed line and the low baritone answers underneath it, which is the specific configuration Cornell described the lightbulb about. This is the only merge in the guide whose precedent is a single song, and the recipe is essentially: do deliberately what happened by accident.

THE FRAME, THE HARMONY AND THE ANSWER

All three at once, split by where each one puts the strangeness.

Three answers to where the weirdness lives, running simultaneously. Soundgarden own the frame: one open tuning found rather than chosen, riff in seven, sympathetic notes droning under everything. Alice in Chains own the vocal: two voices in parallel fourths, written as a single two-note melody and tracked separately. Pearl Jam own the process and the answer: the singer receives the finished track cold with no guide melody, one guitar is locked to a part that never changes while the other floats above it, and the production is dry and forward rather than reverbed. The mechanism that lets all three coexist is Cornell's own, stated plainly on "By Crooked Steps" — "The vocal melody is still in 4/4 while the guitars are in 5" — so the frame is odd, the harmony is square, and they resolve together on a cycle. Add the footnote that all three bands recorded in the same two rooms, London Bridge and Bad Animals, across thirty years, and the triple stops looking like a stretch.
