Wow - I just discovered Malian guitarist-singer-songwriter Habib Koite. Very sweet acoustic guitar playing, very melodic, groovy percussions, a cool voice, great production...
tunes his guitar to a pentatonic scale and plays on open strings.
Bonnie Raitt compared Habib to Jimi Hendrix and Stevie Ray Vaughn.
I'm listening to his cd "Afriki."
