Query: Just the thing

This acoustic jazz guitar/bass album continues to amaze me. Alden's talent and technique are dazzling, and Lesberg really gets things swinging. A must-have if you have love jazz guitar, especially if you appreciate the acoustic archtop guitar sound. Black Beauty is the standout track, but it's misleading to single one song out, they're all incredible.
