Even if he isn't a fan of his music, there's no arguing that jimi hendrix was one of the most influential musicians of all time
regardless of whether or not you think he was any good or not, he had so many techniques that distinguished himself, like his use of the wah-wah, the chord techniques he used, or his use of his thumb to play certain chords. Plus, his stage presence was completely different from what everyone was doing at the time, and I think that influences a lot of musicians today.
I think to dislike him is one thing, but to deny that he was influential is just stupid.
