My idea for a metal band:

Devin Townsend- Guitars/ Vocals (Strapping Young Lad, solo)
Peter Tägtgren- Guitars/ Backing Vocals (Hypocrisy, Pain)
Richard Lövgren- Bass Guitar (Meshuggah)
Martin Axenrot- Drums (Opeth)

Haha that'd be insane to see, they'd all kill each other over creative differences and Martin Axenrot would have a panic attack and lock himself in the closet. It'd be the most brutal album of all time.

I'd just let Steven Wilson do whatever the **** he wanted.

Vocals: Billy Corgan
Guitar: H.R
Bass: Krist Novoselic
Drums: Dave Grohl mutated with Neal Pert mutated with John Bonham

Mike Patton - Vocals
Kevin Shields - Guitar/Production
Omar Rodriguez-Lopez - Guitar
Les Claypool - Bass
Brann Dailor - Drums
Tom Waits - Beat-box
Bez

lead vocals: Eddie Vedder (Pearl Jam, solo stuff)
vocal accompaniment: Stevie Nicks (Fleetwood Mac)
guitar: Jimi Hendrix
guitar: Allen Collins (Lynyrd Skynyrd)
bass: Mike Inez (Alice In Chains)
drums: Bonzo (Led Zeppelin)
keyboard: Ray Manzarek (The Doors)
harmonica: Mickey Rafael (Willie Nelson's Band)
in charge of writing the songs: Bob Seger

Meg White can keep a beat, sure, but she's not that great a drummer.

You'd have some wickedly hilarious videos ;)

I think it was a joke. All of them suck (except Shatner, he's great).

Billy Cobham - Drummer
Tatsuya Yoshida - Drummer
Magic Sam - Guitar
Mark Tilton - Guitar
Screaming Lord Sutch - Vocals
Stanley Clarke - bass
Chick Corea - keyboard/moog
Serge Fiori - backup vocals

And the band will be called Tapirs of Barsoom.

Here's my lineup for an avant-jazz-kraut-prog-funk band called the Lords of Misrule.

Daniel Gildenlow - guitarist, secondary vocalist
David "Fuze" Fiuczynski - guitarist
Edgar Froese - Mellotron
Mattias Olsson - Drums
Chris Squire - Bass, backup vocals
Keith Emerson - Keyboards
David "Jaxon" Jackson - Saxophone
Nils Frykdahl - Flute, primary vocalist
