R&B singer Joe answers a frequently asked question with the title of his new album, Joe Who? Joe Thomas, and asks one with its first single, "Where You At."

The single is not about him, although its title is probably a question he's heard a lot as well: Joe hasn't released an album since 2003's And Then ...

"It's about searching for that loved one who you might of made a mistake with, just saying things that weren't meant to be said at that time," Joe explained of the single, for which he just shot a video. "So now I'm on a search trying to find where she is."

"Where You At" was produced by red-hot Sean Garrett — who has penned #1 hits for Usher, Beyoncé and Chris Brown — and features newcomer Papoose.

"I got a lot of collaborations on the hip-hop side, [because] I'm a huge fan of hip-hop," Joe said. "I got Papoose, I got Nas, I got Fabolous, just to name a few."

Joe's publicist would not confirm other reported guests, but noted that the Underdogs, Cool & Dre and Bryan-Michael Cox are among the producers who contributed tracks.

"I really went out and did everything on my part that I could do to make the best album that I can," Joe said of his new LP, which is due September 12. "I would say it's my best album so far. I expect it to do big things."

He plans to help it along with a tour, although dates have yet to be confirmed. "I tour pretty much every year." he said. "I love touring because that's the biggest appreciation that you can get, when you're performing and someone sings it back to you."

Joe said he's also developing an upscale men's clothing line called J Thomas and a liquor called Sojo. "It's part of the tequila family," he said with a smile.
