The Smashing Pumpkins have dished up an unreleased track, "SuperChrist," for a limited-edition CD that will be made available March 1 at Guitar Center locations, according to Billboard.com.

The compilation disc, which doesn't have a name, was curated by Billy Corgan and the gang — they picked acts that feature Guitar Center employees based on submissions from them.

"SuperChrist" was a leftover track from the Pumpkins' 2007 album, Zeitgeist, and the band has previously played it on tour.

An accompanying video will premiere February 27 on MySpace.
