I'm doing a flute/guitar duo gig today, and we're using "World Music for Flute & Guitar" by Allan Alexander and Jessica Walsh for the bulk of our material.
Anyone got any other flute/guitar collections they'd like to recommend?
Man, there were some Tim Weisberg pieces, but I'm not sure they made sheet music available. In the link above check out number for Guitar Étude. Maybe you don't really need sheet music, just the key for the AABA stuff they do?
