The author is Gregg Miner, and Gregg has an extensive library of harp guitar music. A long time ago I met Gregg when one of my friends Brad Hoyt (a keyboard and harp guitarist as well) hosted a harp guitar convention here in Indianapolis, and I got recruited to help. Gregg and the rest of the artists that were there were extremely approachable, and most of the crowd were musicians (some pretty famous ones, too) checking out one of the more interesting variations of the guitar... and what you could do with one. Fun times.
