Ok, my top seven:
David Bowie (1969-1982) - and a few bits here and there after that
Iggy and the Stooges
Radiohead
Pink Floyd (up to the departure of Roger Waters)
Led Zeppelin
Velvet Underground
Electric Wizard
others: Birthday Party, Pixies, Nirvana, Sunn O))), NIN, Prodigy, T.Rex circa '72, Saints, some My Dying Bride, Mournful Congregation, some Smashing Pumpkins - alterna-rock usual suspects i guess, for the most part...
