As mentioned in this previous thread here, WBGO launched an HD2 channel called The Jazz Stream in late January. The 2nd channel promotes emerging jazz artists and styles along with some classics and highlights from interviews, live broadcasts and studio sessions.
Two articles about the channel are on the station's blog: here and here
Both articles have a link to the streaming audio player: http://www.wbgo.org/internal/mediapl...acker=20120607
