You don’t see a whole lot of rap covers, since the genre is so bound up in individuality and self-referentiality. The rough equivalent, I suppose, is rappers freestyling over each other’s tracks, and hardly anyone even does that anymore. But during a recent visit to the BBC’s Live Lounge, Big Sean gave the straight-up cover a shot. Along with his live band, he performed his own version of his mentor Kanye West’s 2007 Graduation album track “I Wonder,” only making minor lyrical tweaks. the logic, I guess, was that we needed to hear two different rappers tell you that something in your blouse got them feeling so aroused. Watch the performance below.
