Over-rated formula pop early on, and drug-inspired concept albums in the later years... Yawn.
They may have been great with bringing us stuff like feedback, distortion, and other studio advances, which I appreciate, but they also helped to give legitimacy to drugs and the hippie movement.
Screw 'em.
For feedback, distortion, and other improvements to rock and roll, you've got to turn to Howlin' Wolf, Link Wray, Travis Wammack, Dick Dale, and Davie Allan (and the Arrows).
Link Wray got banned for an instrumental cut long before the Beatles even considered playing rock and roll. That same single (Rumble) got Pete Townsend to pick up a guitar.
All of them except for Chester Burnette (Howlin' Wolf) are still alive and still playing (and still recording new music). It took Beavis & Butthead to get Dick Dale on MTV despite his Miseralou leading the smash film Pulp Fiction.
Screw the music industry. They screw over the talented performers and push pap.
