So I was very happy to discover that the Smalls Club’s website features a live webcam with real time video and sound. Broadcasting times is from 7:30 p.m. to 3:30 a.m. Which is usually too late, or too early for me: due to the time shift, the shows end at my breakfast time.

The legendary Village Vanguard, world-known for many great recordings that have been made there, has a live radio show at WBGO. Some of the concerts are available for download as podcast.
