Martin Tallstrom is a country and fingerstyle guitar master who shares all his techniques and tips to less accomplished guitar players (e.g. me) for free at his website. I was raiding his site very late last night to bone up on my Nashville chops, and stumbled across this elegant rendering of the Twin Peaks theme.
I'm something of a Twin Peaks geek, and every couple years I take a long weekend and watch the whole series front to back. I'm blown away by Angelo Badalamenti's score -- alternately warm, menacing and spunky, every time.
Tallstrom also has a fine version of Laura Palmer's theme here.
