It's been nearly three years since Louisiana rapper Lil Boosie dropped his debut Bad Azz, but he and his label Trill Entertainment have been in the lab hard at work are are ready for his return with Superbad: The Return of Boosie Bad Azz in September.

To mark his return the 25-year-old rapper, hailing from Baton Rouge, is unleashing the new track, "Better Believe It," which gets an assist from labelmate Webbie and Young Jeezy. It's the project's lead single.

Produced by Trill Entertainment's in-house producer Mouse On The Track, the new single celebrates Boosie's success since dropping his debut, overcoming pain and adversity that has plagued him most of his life. Webbie and ATL rapper Young Jeezy give their own intense lyrical testimonies about surviving urban life, as well. Currently, "Better Believe It," is making its rounds in the South and Midwest, and starting to spread.

Superbad is the follow-up to Boosie's gold-selling, critically acclaimed 2006 debut, Bad Azz. According to the rapper, the album promises to improve on the formula of the conceptual diversity that made his first effort so successful. There is literally a song on here for everybody, he says.

"With [Superbad] I'm still hittin' 'em from all angles," explains the rapper. "I got the women songs, I got the gangsta songs, I got the love songs; something for everybody. It's just a classic album."

The 16-track effort boasts production from the likes of The Runners, Mouse on the Track, and B-Real, among others. Guests include the aforementioned Young Jeezy and Webbie along with Trina, Bobby V, Fox, Lil' Phat and Mouse.

Although Boosie is best known for the breakout singles, "Wipe Me Down" featuring Webbie and Fox and "Zoom" featuring Young Joc, he's been a certified stars in the southern underground for years.

The rapper started his career back in the late 1990s when a mutual friend introduced the 15-year-old to Baton Rouge's legendary rapper C-Loc. Impressed with Boosie's magnetic personality and rhyme skills, C-Loc took the teenager under his wing, signing him to his indie label C-Loc Records where he made his first appearance on wax with C-Locs's It's A Gamble LP in 2003. That same year he released his underground debut LP, For My Thugz, followed by The Youngest of Da Camp in 2004. Just as things began to move for the young rapper, C-Loc was arrested and subsequently incarcerated, resulting in the label folding and Boosie without a deal.

But things took a turn for the better when he hooked up with up-start record label Trill Entertainment and they introduced him to the late great Pimp C of the legendary duo UGK.

"I did a couple of songs with Pimp C and got with Trill and everything started taking off," says Boosie.

From there, he released a series of mixtapes and street albums, which in turn, helped him land countless shows throughout the south.

Today, Superbad is on the way, and Boosie is looking to further extend his reach into the hip-hop audience. "There's not one song on here that you just can't listen to," boasts a confident Boosie. "This album is just versatile. This CD is the truth."

Boosie is currenty on a promo tour, and recently shot a music video for "Better Believe It" in Baton Rouge.

Superbad: The Return of Boosie Bad Azz is slated for release September 15.
