Atlanta-based rapper B.o.B rose from the underground quickly after releasing his 2010 debut, The Adventures of Bobby Ray, where he used a savvy list of guest pop stars like Bruno Mars and Paramore’s Hayley Williams to round out the record. The follow-up, 2012’s Strange Clouds, mined from the same formula and added Taylor Swift, Nicki Minaj, Chris Brown, Lil Wayne and T.I. to his list of collaborators. But his third album, Underground Luxury, aims to show a different B.o.B. side. He says it’s a return to his grittier rap roots and so far, he’s kept up that promise with the two lead singles, “HeadBand” with 2 Chainz and “Ready,” which mixes his raps with Future’s off-kilter warbling. B.o.B recently spoke with Rolling Stone about Underground Luxury, reteaming with Chris Brown, and his long-mooted rock EP.
