I just came across an interesting radio programme called Rare Frequency "devoted to experimental, electronic, improv, noise, and quasi-pop music, with the occasional non sequitur thrown in for good measure."It's hosted by someone named Susanna and the episodes are podcast (although, she only provides an iTunes link, which is annoying).
Trust me, this won't be for everyone, so to get a taste of it, you might try listening to Susanna's last.fm station.
