Great recordings by players with other bands/artists

Some of my favorite solos are by artists playing with different artists they are not normally assosiated with-

Jack Bruce on Frank Zappa's Appostrophe

Frank Zappa's guitar solo on Grand Funk's song Out To Get You.

Jaco with Joni Mitchell

[gweimer]

Eric Clapton on "While My Guitar Gently Weeps"

SRV on all of David Bowie's Modern Love

David Gilmour and Ian Paice behind Paul McCartney on Run, Devil, Run

Everyone behind Eno on Here Come the Warm Jets.

Flea on the first Mars Volta full length.

Fleetwood Mac on the Eddie Boyd Blue Thumb lp.  The Yardbirds on the Philamore Lincoln lp.  McVie and Fleetwood on Werewolves of London.  The Beach Boys backing up Elton John and Chicago on vocals, and Flo and Eddie vocals all over things.  George Harrison on Basketball Jones with Cheech and Chong.  There's a bunch I like.
