Unappreciated rock bands...

Martin Briley - Great artist - mostly studio for others - "sit around and drink a few more beers, until the memory disappears"

Gamma - Part of a circle of guys who were in several bands with Ronnie Montrose

The Paul Butterfield Blues Band - Mike Bloomfield is probably one of the most under rated guitarist of all time (not saying lightly) This band changed the style of blues music, 1st band with the raga style solos that became part of the late 60s onward. Very powerful. Oh, Elvin Bishop was the rhythm guitar and sometimes duel lead. And he is still going. Their first two albums are awesome, Bloomfield left after that to form Electric Flag. Which he followed up with the "super sessions" with Al Kooper and than went solo
