Rock band Radiohead has already pushed the envelope in the past year by first releasing their new album under a pay-what-you-want price scheme in October, and then calling on fans to create a music video for any of the album's songs in March. Now the band is at it again, teaming with Apple, makers of iTunes and GarageBand, to launch a public remix contest. The contest offers up the single "Nude" from the album for remix. The band has for sale on iTunes "stems" for the bass, voice, guitar, strings/fx and drums for the song and anyone who purchases all five gets access to a GarageBand file that can be opened in GarageBand or Logic. Until May 1st, the public can vote for their favorite remix, and remix authors can use a MySpace or Facebook widget to allow fans on social networks to vote for them. The prize, though, is just that Radiohead promises to "listen to the best."
