T.I., Ludacris Join Big Boi on 'In The A': Listen

Big Boi performs during day one of the Austin City Limits Music Festival Day One at Zilker Park on September 16, 2011 in Austin Texas.

Atlanta's finest are repping for their hometown on Big Boi's "In the A."

The new track, the latest from the OutKast MC's upcoming solo set "Vicious Lies and Dangerous Rumors," corrals Ludacris and T.I. for a hard-charging song driven by blasting horns.

"We official ATLiens," T.I. raps in his tightly rhymed verse, referencing Big Boi's 1996 OutKast classic, but the swaggering track's too heated for nostalgia.

T.I.: The Billboard Cover Story

With "Vicious Lies" still a few weeks off from its Dec. 11 release, Big Boi's already shared tracks "Lines" and lead single "Mama Told Me" on his SoundCloud account. "In the A" had over 30,000 plays on the service after just a few hours on Monday.
