Zac Brown has been working on a secret side project.

 

The Zac Brown Band is heading into the studio this winter to crank out some new music. The band says their next album is returning to their roots, and will feature tunes similar to those heard on their debut album, The Foundation.

Zac has also been working on a secret side project. He's in another band called Sir Roosevelt, and they just released the first single off of their upcoming album. So far, Zac Brown is the only known member of Sir Roosevelt. The rest of the band members remain a mystery.

Listen to 'Sunday Finest' by Sir Roosevelt below. WARNING: Some of the lyrics are NSFW.
