So many, so many....besides early Zep, Cream, Stones, & Beatles:
The Who!
Also, Humble Pie, the Yardbirds, anything Jeff Beck, The Small Faces, Dave Clark 5, The Pretty Things (way under appreciated), Pink Floyd (but mainly with Syd Barrett), Free, The Creation, early Mayall, early King Crimson, Dr. Feelgood, The Inmates, The Shadows, early Fleetwood Mac (Peter Green), Incredible String Band, Pink Fairies, Procol Harum, Twink, July, Apple...Kinks & Animals, too. Dusty Springfield, not a group, but still...
Spooky Tooth's "Spooky Two" album was brilliant as well as their version of I Am the Walrus.
Taste (Rory Gallagher) and Them, but they'd be Irish.
