I recently discovered the “Night Lights” Classic Jazz Radio Program, an hour-long weekly jazz program produced by Indiana University’s public radio station. It’s marvelous, and there are five years’ worth of archives available on the web that you can listen to at any time.
Each program focuses on a particular artist, particular period, and/or particular style, combining some context and discussion with a selection of some of the best recordings. I just finished listening to the January 2007 broadcast on the excellent but obscure tenor saxophonist J.R. Monterose, as well as the August 2009 broadcast on the Claude Thornhill Band. Both were excellent. If you’re interested in learning more about jazz, or you want to hear more about a particular jazz musician or style, the program is well worth checking out.
