In the '60s, rock'n'roll was still pretty new, and fresh ideas were appearing daily. Radio here in L.A. was wide open, with B. Mitchell Reed at KFWB and later at KPPC playing a Beatles song, followed by a John Prine cut, leading into a Cream recording, then Buffy St. Marie. No categories were 'taboo', all was worthy of hearing.
Into this mix in 1964 came The Yardbirds, one of the most unique of the "British Invasion" bands. While most notable today for spawning 3 of the greatest rock guitarists ever (Clapton, Beck, Page), they should be remembered for some pretty original music.
I saw the last version with Jimmy Page, at the Fillmore in San Francisco in '68.
Here are 3 parts of a documentary about The Yardbirds. Enjoy.
