David Grisman, aka "Dawg"

Mandolin monster. In a good sense. Played with Bill Monroe, Tony Rice, Stefan Grapelli, Jerry Garcia, Andy Statman, Mike Marshall, and others. And a very personable, approachable man too.

addendum: Turns out there is another blipper at the mandolin symposium, a Fine Finnish Fellow named Jaakko (pronounced Yak---ko, where --- is a significant pause). Infiltrate the world!
