Jimi Hendrix
In my teens, I was lucky enough to see Jimi Hendrix live and the whole experience had a profound effect. An audience of 800 people in a space fit for 200 unfortunately resulted in an earlier than expected end to the gig.

Best songs for me were:
Hey Joe, The Wind Cries Mary, his version of Dylan's All Along the Watchtower and of course Purple Haze.
