Just a year after "Vital," its October 2012 release, Anberlin is back with a special edition of that album -- "Devotion: Vital Special Edition" -- which will see an Oct. 15 release on Big3 Records. Ahead of its release, the band has dropped a new song off the album, "IJSW," for which Billboard has the exclusive premiere.

According to frontman Stephen Christian, the song didn't form in the same way most Anberlin tunes have in the past.

"This song is as close to Jack Kerouac Anberlin will ever come," the frontman said. "I just pushed play on the demo and just sang whatever came to mind. I sent it to the rest of the guys under the guise that I was 'sold on the melody lines but the lyrics were just free form' (hence the first line of the song 'I can't help but say whats on my mind'). [Guitarist] Christian [McAlhaney] and the guys emailed me immediately and said not to touch them... guess I should have been making stuff up our whole career."

"IJSW" is one of three new tracks from "Devotion," which also includes "Vital" b-sides and a second disc of live material from the band's acoustic show in Williamsburg.

The band recently embarked on a co-headlining tour with The Maine, which started Oct. 2 in Albuquerque, N.M., and will run until Nov. 5 in Orlando.
