One of my favorite bands is a folk/bluegrass band called The Punch Brothers. Well worth your time to check them out. I recommend the tracks "Magnet", "New York City", and "I Blew it Off" for starters. Anyways that's another topic for another posting.
Chris Thile, who is the lead singer of the Punch Brothers has released a solo recording of himself performing Johann Sebastian Bach's Sonatas and Partitas on the Mandolin. It's beautiful, and I really want to share a performance.
