Got country and bluegrass? These guys sure did to the point where their frontman studied the genres at the feet of the legendary Bill Monroe.
Ladies and Gentelmen, from the Bay Area, it's the Grateful Dead on the Tom Snyder show performing, "Dire Wolf".
(ed. note: for those who wish to quibble genres, their studio version of this song features the pedal steel guitar giving it much more of a bluegrass feel rather than the straight-up country vibe you are listening to right now.)
