Led Zeppelin
Rolling Stones
Beatles
The King, for sure... Hell he more or less started the white boy rock'n'roll thing, didn't he?!?!
KISS, absolutely - they were viral man!!
Grateful Dead, believe it or not, people dedicated their LIVES man....
U2
Nirvana, although they reached "bigger than life" kinda after the fact...
Out of all of them though, Led Zeppelin existed in a time where there was already a paradigm shift underway socially, drugs were getting better, freedom was an actual choice, and the innate 'want' to get on with 'heavy metal' just sprouting. They were gods in their prime - absolute gods.
