The 25th anniversary of "ATLiens," the cinematic hip-hop masterpiece that catapulted OutKast (André 3000 and Big Boi) into the mainstream stratosphere from the Atlanta underground music scene, is being celebrated with an expanded edition of the album.

"ATLiens (25th Anniversary Deluxe Edition)" includes the complete original album along with a collection of 14 previously unreleased instrumental tracks.

This new expanded 25th-anniversary version was mixed in Hi-Res 24-bit sound.
