What band members do you think would make the greatest "Super Group?"?

Answer 1

~Robert Plant, Syd Barrett and Sting (vocals)
Eric Clapton, Jimmy Page and Robbie Robertson (guitar)
Roger Waters and Sting (bass)
Ginger Baker and John Bonham (drums)
Billy Preston and Richard Manuel (piano/keyboard)

I don't know how long this group would actually last with the egos involved, but for me, it would be one amazing concert.

Just for fun, I'd put together a jazz group consisting of:
Billie Holiday and Sarah Vaughan (vocals)
Miles Davis and Maynard Ferguson (trumpet)
John Coltrane, Charlie Parker, Sonny Rollins and Joe Lovano (tenor & alto sax)
Gerry Mulligan (baritone sax)
Charlie Mingus and Scott LaFaro (bass)
Thelonious Monk and Gil Evans (piano)
Kenny Clarke and Elvin Jones (drums)

Answer 2

~For a "Super Band":
Glenn Miller
Gene Krupa
Harry James
Benny Goodman
Artie Shaw
Pete Fountain
Al Hirt
Louis Armstrong
Tommy Dorsey
Charlie Mingus
Dexter Gordon
Theolonius Monk
Dave Brubeck
Stan Getz
Jerry Dorsey
Buddy Rich


vocals
Etta James
Nancy Wilson
Mel Torme
Laverne Andrews
Count Basie

Answer 3

~It was done:
Eric Clapton
Steve Winwood
Ric Grech
Ginger Baker

Called themselves Blind Faith.

I'd add, for variety and the conflict of guitars,
Jeff Beck
Jack Bruce
Jim Capaldi or Dave Mason

and just to mess everyone up and to sneak in a few genius power licks, Jimi Hendrix

Gotta have some fighting at the low end, so on bass
Klaus Voorman and Bill Wyman

For lyrics and vocals,
Pete Stampfel
Justin Hayward

and for the slower back up drums, John Bonham

Keyboards
Ray Manzerak
Billy Preston
Billy Joel

In the studio only, for extra voice,
Janis Joplin or Grace Slick
Jim Morrison or Ian Anderson

And if they want to do some Blues, not that they can't already,
let's toss in John Baldry, Kenny Wayne Sheppard, Johnny Lang and Johnny Winter (leave Edgar home)

Of course, they wouldn't last more than one gig on the road and the studio tracks would have to be laid down separately because Clapton can't play with anyone for long and Gracie and Janis would be too stoned to finish. The artistic argument between the others would pretty much preclude getting any work done, until they were done work and started to jam.
But you are probably looking for someone contemporary. Sorry, there ain't nobody out there that holds a candle to these folks.

This all assumes you want rock.
For mellow, stick with
John Sebastian
James Taylor
Laura Nyro
Carole King
George Harrison
Neil Young, but only with Joni Mitchell to cover his low end
If ya gotta have drums and don't want a studio drummer, toss in
Phil Collins and Don Henley
with Bob Dylan doing the writing and Roger McGuinn doing his singing for him.

Answer 4

Vocals-Kohl Hegmann, Another Day Late
Drums-Dan Alsheimer, Nothin' Yet
Guitar-Jimmy Page, Led Zeppelin
Bass-John Zindar, IY

Answer 5

Dweezil Zappa
Jason Bonham
Shooter Jennings
Roseanne Cassh

Answer 6

Lead vocals: Freddie Mercury
Guitar: Steve Vai
Bass: Victor Wooten
Drums: Carter Beauford

Songwriter: Dave Matthews
Sure he's not the best, but he's one of the few who could cater to the differing creative needs of this group.

Answer 7

Tommy Lee, Sammy Hagar, Richie Sambora. I can't think of another bass/guitarist, so I will leave that to another time.
