Listening to Zane Lowe on Radio 1 this evening, I heard a song that completely blew me away: "Hide and Seek" by Imogen Heap from her album Speak For Yourself. It's a far out, haunting, electronic a cappella that I don't completely understand, but can't get out of my head. There isn't even a melody to it--it's just there, and it's awesome.

If you've got RealPlayer (hack, spit) installed, you can listen to Zane's show from this evening (26 July) on the BBC web site for the next week. The "Hide And Seek" is on about 40 minutes in.
