T-Pain recently put out a new mixtape, The Iron Way, with the help of DJ Drama. While fans are patiently waiting for his next studio release, Stoicville, the producer recently shared a trailer for the upcoming documentary about his life titled Bigger Than Pain. The doc is due out April 29, HotNewHipHop notes.

The rapper's work effort and artistry are on full display in the clip below. There's even a brief scene of T-Pain performing a solo version of "Buy You a Drank (Shawty Snappin')" from his NPR Tiny Desk show.

"Of course I go broke for this music ... in order to go somewhere you've never been, you gotta do something you've never done," he says.

T-Pain took some time off from music following 2011's Revolver album, which hit 28 on the Billboard 200. He dropped the title track from his new album last year, though, following it up with "Coming Home" and "Keep On."

"Stoicville is more truthful to me," he told Larry King about the album. "It's things that's in my heart instead of trying to make hits ... It's not about if people get it or not. It's about if I'm singing from my heart and making lyrics that resonate with me and not just making people dance in the club all the time."

Hopefully his period of creative rejuvenation was productive because his last album received mixed reviews.

"Still leaning hard on Auto-Tune, Pain concocts song titles to rival R. Kelly and backs them up with slow-jam indulgences testifying to a life of unfettered pleasure," Rolling Stone wrote.
