Just before the curtain went up on our live show in Los Angeles, Jad and Robert carved out a little stage time for a sneak peek at next week's Colors episode.

We're so excited about our upcoming Colors show--an hour devoted to the mysteries of rainbows, wavelengths, and perception--that we wanted to do something a little unusual. Something we've never done before. We decided to take on a musical experiment on a much bigger scale than anything we've ever tried.

So we picked out a big batch of songs about colors (from Blue Monday, to Pink Moon, to Yellow Submarine), then we asked a passel of adventurous artists (from all over the spectrum--seriously, we've got indie rock, blue grass, funk, gamelan...) to record some technicolor covers.

What came back has us seeing stars (in a really, really good way). So here's a taste--including a wonderfully trippy live version of Bein' Green by Reggie Watts. Stay tuned for Colors next week, and if you want to help support Radiolab in the meantime and get access to mp3 downloads of some of these covers, check out our new digital membership program Lab Partners. Thanks everybody!
