Where are the best places to find good underground music?

does anyone know any good websites with a broad variety of free sheet music? particularly Ben Folds.

Going to cuba soon, really interested in the african culture and where to find it, we are traveling to havana and santiago de cuba. are there any interesting sights, people, shops clubs or bars that would help us see this.

looking to the group back-on's music. they are a japanese band. there song chain is the opening theme song to the anime air gear. any site, legal or illegal will do.

I was wondering if there was a good website I can visit to find sheet music, or music notes for songs. Hopefuly with tabs for drums, guitar (Chords will be helpful too) and keyboards + Piano. (Please no spam/virus websites) Thanks for your help!
