Hendrix got a fair amount of crap from the brothers for his rockin ways. He was also shunded by the old bluemen. Hendrix actually had a lot of R&B experience, playing with the Isley Brothers, Little Richard and others. I read somehwere years ago they, "the brothers" used to bust his balls and say "when you comin' home?" I believe he was in this process when he started Band of Gypsys, you can hear more soul but you can still hear Hendrix. I also read he was very tired of demands from fans to play his old bombastic songs and smash his guitars and was tired of everyone feeding him drugs, he wanted to forget the psychedelic stuff and expand his musical abilities, but I think he was a bit lost and bewildered, burnt out as well. He was supposed to hook up with Billy Cobham and Jan Hammer but never got the chance. So we had Tommy Bolin on Cobhams "Spectrum" album which isnt a bad thing at all but Hammer influence would have done Hendrix alot of good and we would have had the opportunity to hear Jimi playing some fusion.
Vaughan stayed with the blues and boogie format except when covering Hendrix and perhaps a touch of jazz with songs like Riviera Paradise, which is actually my favorite pick, it totally emphasizes his expressive and loose feel ability.
I still need to fill out my Vaughan collection, I only own CSTW and In Step.
If anyone knows of any unmentionable download sites you need to find yourself a copy of Stevie playing and SINGING Jimi's Little Wing, there are many versions. Typically all instrumental but the one I have has him singing and the improve is flawless and if you are a die hard Hendrix/Vaughan fan such as myself can almost bring a tear to the savage eye, the sound quality is excellent, vocals will melt you and he was definantly in "the zone". Either at the beginning or the end it says "brought to you by simple accurate .com" or something of that nature. Funny thing is, I found it listed under nearly every great guitar player except Vaughan. Names like Beck, Trower, even Steve Morse, but there is no doubt... it is "the one and only"... no one... I repeat... NO ONE else could play like that.... except for maybe one
