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.
If you're interested in the tradition of jazz and discovering unfamiliar music at the same time, check it out
