Just to add two not mentioned if we are truly talking only about cumulative blazing talent:
Mahavishnu Orchestra (McLaughlin/Cobham/Hammer)
Weather Report (Zaiwanul/Pastorius/Shorter)
and support for:
Beatles (for breaking new ground)
Floyd (best Stadium guitar/angst rock)
ELP (instrumental speed and agility)
Supertramp (Rick Davies was a genius)
SRV dbltrbl (nobody touches Stevie and JMac on guitar, though Gilmour is close)
