Topic: Music on tv
In trying to find things to dvr so I can watch them when working out I came across Sun Studio Sessions on PBS. In particular the Delta Blues Experience, 2 episodes. It was blues so you can't go wrong.
During that show there was an ad for Bluegrass Underground. Bluegrass isn't my thing, but the clincher is that these concerts are held in a cave 333 feet below ground. Cool idea, I'll have to watch an episode just to see what it's like.
