No doubt Alvin Lee had very impressive raw energy and drive ... I really like Alvin Lee and Ten Years After. But he was a kinda sloppy player, and used some "tricks" ... well "tricks" is not the right word, but similar to Neil Young, he did simple things that SOUND complicated if you know what I mean
BTW ... Neil Young has gotta be technically the worst guitar player in popular music.
I think I'm gonna get some incoming here ... better go get LABF
