A special recording of Radiohead's '15 Step', which features the Trojan Marching Band, is to be released.

The song was recorded during rehearsals for the 2009 Grammy Awards, where the two acts performed together on stage.

It forms part of the University of Southern California's Trojan Marching Band's new double-CD, 'Trojan Legacy'.

At present, the album is only available via the university's online bookstore.

Radio won best alternative album for 'In Rainbows' and best boxed or special limited edition package for the discbox at the Grammy Awards in February.
