Radiohead's USC Trojan Marching Band Collaboration Released

Earlier this year, Radiohead joined forces with the University of Southern California's Trojan Marching Band for a unique take on the 'In Rainbows' track '15 Step' for the Grammy Awards telecast.

Now, a rehearsal version the collaboration -- recorded in advance of the televised performance -- is surfacing on a new double CD of material by the Marching Band entitled 'Trojan Legacy CD -- 40 Years of Dr. Arthur C. Bartner and the Spirit of Troy.' However, fans seeking out the track will only be able to find it through the USC Bookstore.

In addition to that track, the disc boasts an abundance of Trojan efforts and spans 40 years. It counts versions of '70s songs like Free's 'All Right Now' and the Edgar Winter Group's 'Frankenstein,' their 'Tusk' effort with Fleetwood Mac and more recent material, including two System of a Down covers and an Offspring tune.
