Asher Roth

28-year-old Philly rapper Asher Roth recently parted ways with Justin Bieber's mentor-manager Scooter Braun, which presumably means we won't be getting that Bieber/Roth duet we've all been hoping for. Never mind: you can catch A-Dawg performing his bouncy, nerdy hip hop in London tonight instead. He'll drop tracks from his new album 'Retro Hash' – one for the anagram fans.
