I've recently discovered a very good online series of radio broadcasts called Nightlights. The host is David Brent Johnson, and the programmes, while clearly scripted, are very well put together under different themes - Benny Goodman’s Interlude in Bop, Young Wynton: Early Marsalis, After the Vanguard: the Return of Bill Evans, Jazz Impressions of Paris, Too Little, Too Soon: Booker Little - etc.
I've heard some really good music that I wasn't familiar with and the whole idea is really intelligently and musically done.
