Last night (November 29), Grand Hustle's B.o.B celebrated his forthcoming Strange Clouds album with a special concert held at NYC's famed Bowery Ballroom hosted by Hot 97's Peter Rosenberg. With a couple surprises lined up, the highlight of the night came when the instrumentals for the tantalizing "Bet I Bust" dropped and Bobby Ray brought out his first guest, a hooded T.I., sending the packed crowd into a frenzy.

"Yeah, hey, gather round, front and center, the King finna enter/The room when the boom hit the booth, I deliver," T.I., sporting a black skully hat and a Louis Vuitton knapsack, spat. "You mind if I flex on these people one time?" T.I. asked his protégé before rocking the crowd with his bass-rattling single, "I'm Flexin," this time bringing out another familiar face.

"Hold on, how many chains I got on?" Tip asked the crowd as he introduced the next performer. "Can you count? Let me bring [out] 2 Chainz!" When the Drumma Boy-produced banger "Spend It" boomed from the speakers, it was clear the A-Town came to shut NYC down. "Congratualtions to the game, A-Town is back," Tip proclaimed.

Decked out in all-black gear-studded black leather jacket, black tee, two gleaming gold chains, and his signature specs, B.o.B flexed his catalog of hits including joints like his "Teach Me How to Dougie" remix verse, "I'll Be In the Sky", "Satellite" and "Don't Let Me Fall." On the latter two, Bobby showcased his musicianship by breaking out both the piano and guitar, respectively.

"Soon as I enter/You know who it is-a/It's the representer from the east-side of Atlanta," the ATLien bellowed on "Batman Flow," off his 2010 No Genre mixtape.

As the clock struck a little past 11:00 pm, Bob pulled some lucky fans on stage to join him for "Magic" which then segued into "Airplanes" and eventually the fitting closer "Strange Clouds." Although a release date has yet to be confirmed, anticipation for Strange Clouds may have just reached another level after last night's star-studded affair. —Ralph Bristout
