Their debut album is less than four months old, but that's not stopping breakout country newcomers Big & Rich from readying a CD/DVD set for their growing legion of faithful followers. Due Oct. 26 via Warner Bros. Nashville, "Big & Rich's Super Galactic Fan Pak" will boast a mix of previously unreleased tracks, remixes and acoustic and live recordings.

The five-track CD includes two songs left off the duo's debut, "Horse of a Different Color" -- "Never Been Down" and "The Bob Song." Rounding out the disc is a dance mix and a live version of the album's "Save a Horse (Ride a Cowboy)" and an acoustic take on "Drinkin' Bout You" that runs nearly nine minutes.

The DVD sports a live performance captured at Big Al's Buffalo Club in Deadwood, S.D. In addition to renditions of eight tracks from the debut, Big & Rich also deliver "The Joyce Song" and "Big Al's Buffalo Club Medley," made up of "Disco Ball," "Limo Larry," "Say Ooh," "Chair Ride" and "Blow My Mind."

Additionally, the DVD includes a photo gallery, the video for "Save a Horse" and an on camera interview the pair did with Launch, Music on Yahoo!

It has sold 1 million copies in the United States, according to Nielsen SoundScan. Second single "Save a Horse (Ride a Cowboy)" made it to No. 11 on the Country Singles & Track tally last month.
