Here's my 2 cents to the wealth of suggestions already put forth on this thread. 1. Jon Gindick has a set of tracks for harmonica with 7 positions playing (www.gindick.com) 2. Dave Barrett (Harmonica Masterclass) has produced a CD called "Sittin in with the Greats". Both these CDs are high quality although I am less certain whether you'll be needing it long term. Cheers!
