Way back in 1979, I had the opportunity of taking some bass lessons from Kenny Aaronson who started playing with Johnny Winter in the early 70s, but went on to team up with Rick Derringer to form the band "Derringer". Later he played with Billy Squier, Billy Idol and others. He was one of the first white guys to incorporate slapping into rock bass lines. He is not well known, but is a great bass player and was a great teacher. One of these days, I'll have to go to one of his gigs and re-introduce myself. Who else deserves to be on this list?
