I've encoded the Calais Consort's appearance on WMNF's Live Music Showcase, and now have it up on my Web site for anyone who's interested.
I've put it up as both the entire show and as individual clips of just the songs. If you want to hear the entire show, and have broadband, I highly recommend the Ogg Vorbis format, as it has about twice the quality for a couple of megabytes less. The clips are encoded at a higher quality than the entire show.
