On Saturday night, Hot 97’s Peter Rosenberg celebrated his birthday with a HUGE concert in Brooklyn’s Williamsburg Park. Meek Mill, Odd Future, Schoolboy Q and World’s Fair rocked for the massive crowd, with special surprise performances from Joell Ortiz, Flatbush Zombies, Travi$ Scott and Fabolous. Our very own Funk Flex had a set on the 1’s and 2’s as well. If you missed out, check out the recap in photos and video. Happy birthday, Rosenberg!
