God damn it, y'all need some roots music. American folk, country, and blues has produced some sublime stuff. Rev. Gary Davis is one of the most mindblowing guitarists I've ever heard, between his virtuosic technique, colorful sense of tonality and refusal to "cheat" (meaning he emphatically insisted on never using attachments like capos or slides to acheive those kinds of sounds). To top it all off he was a blind man, excellent singer, and a titanic influence on American rockers of the 60's like Bob Dylan and The Grateful Dead. There's Lead Belly too, another virtuosic guitarist, the difference being he was a folk singer, he wasn't blind, and played a 12 string, not a 6 string. Can't forget Charley Patton either, great guitarist, an influence on almost every great Delta bluesman, and the owner of one of the fiercest, low and growly sets of pipes in blues history.
