Query: It's a great album, but you MUST see this guy live

The album, the music and the lyrics are all well above average. But if you ever see him live, you'll have a whole new appreciation of what JA does. What you hear on the album (if it's like it is live, and I think it is), is all him. No background vocalists, no additional instuments (except the occasional harmonica, also played by JA). And he does it all in real time with no tape. Just JA, a guitar, a harmonica, a mike, some petals and a sampling machine. The drum sounds are him hitting the guitar, sampling it, and replaying it.A remarkable live performance.
