I can think of two:
The Yardbirds: Eric Clapton, Jeff Beck, and Jimmy Page.
James Gang: Joe Walsh, Dominic Troiano, and Tommy Bolin.
Can anyone think of others?
In case you don't remember Tommy Bolin, listen to his epic solo on "From Another Time" from the James Gang Bang album. His fusion work on Billy Cobham's Spectrum album is also damn impressive. You can listen to "Quadrant Four" from that album here. Unfortuntately, like his own hero Jimi Hendrix, Bolin died too young - age 25 - of a drug overdose.
