Under Raps Radio on the San Francisco-based Internet station Radio Valencia is hosted by local selectors The Cosby Kid, Mad Vatsky, and Megabusive, but they all prefer to let the music do most of the talking.
Unless they have a special guest star, the crew makes minimal announcements, filling the time with as many tunes as possible. Listening to it will probably give you hope for the present and future of the Bay Area hip-hop scene as they curate the smart rhymes and the dumb beats. (That's not bad meaning bad, but bad meaning good, for the record.)
The show airs at midnight on Wednesdays, but you can listen to all episodes on demand on the site's archives.
