Check out Inca Son @ Incason.com. I have seen them on several occasions at festivals and public events in Boston. They are wonderful, and always draw sizable audiences. I've picked up one of their cds at these events, but I think they're also available on-line.
Native American Music
My significant other's father just bought a wooden "flute" which looks just like one of those recorders they used to make us play in grade school. Anyway, he's just nuts about this thing and keeps calling it his "Indian flute." He's interested in finding some Native American music that incorporates woodwind instrumnets. Do you have any leads? Thanks.
