British rockers Radiohead are giving their fans the opportunity to make the music video for their next track. The band made history last year (07) when they released their seventh LP, In Rainbows, online as a pay-what-you-want download. And now the five-piece is teaming up with TBD Records, Cartoon Network's Adult Swim and animation Web portal Aniboom.com to launch an online contest inviting fans to produce an animated music video for any song from the album. The competition closes on 27 April (08)
