Wishes came true for students hoping to see some synthpop in the Rathskeller on 11/11/11. The Brooklyn-based band The Bloodsugars visited the College for the second time in two years on Friday night. The band should have felt right at home in the Garden State: Its music was featured on an episode of “Jersey Shore.” Mad Feather Group, a band based in Jackson, N.J., opened the show with its folk-funk style at this CUB-sponsored event.
