I thought I noticed this the other day on the PT Boards, but I guess I never posted anything about it.
NPR has always been known to serve up great music in my opinion. I just noticed their show World Cafe from WXPN has been running two days of great music in a row, yesterday with Mike Gordon and Leo Kottke and today with Trey Anastasio.
You can listen to these with either Realplayer or Windows Media Player. Enjoy.
