Yes Wings, most significant. Jeez, the list should be more than 4.

For heavy rock, it's Purple.
Psychedelic-Mood rock, it's Floyd.
Doors for putting it on the map.
The Who for being on the front end of the melding of Guitar & Synth
EJ for piano.

Well, that's 5.

Styx, Devo & Boston & Edgar Winter had their day, & were awesome, but followed in the wake of the names above. No one mentioned the B-52's.

Pink Floyd
Dream Theater
Porcupine Tree
The Doors
