The pop duo Karmin broke big last year with a string of clever, immensely sassy covers of hits by acts such as Lil Wayne, Nicki Minaj, Foster the People, Katy Perry, Chris Brown, Lady Antebellum and LMFAO. Their videos became viral smashes on YouTube, which led to several television appearances and a contract with Epic Records, who will release the band's first album of original material this spring.
