B.O.B. was the headlining act at Perez Hilton’s One Night In Chicago Lollapalooza kick-off party last night at the Hard Rock Hotel. Bobby Ray ran through most of his debut album as well as a couple mixtape favorites. Here he’s joined by homeboy Playboy Tre for “Bet I Bust” and below he goes in on “Past My Shades” sans Wasalu. B.O.B. puts on one hell of a live show and if you’re at Lollapalooza today make sure you drop in to see him.
