Many of you might be surprised by this collaboration of blues/rockers The Black Keys and Wu-Tang member RZA, but this would not be the first time these guys worked together. A few years back, The Black Keys ventured into hip hop under Blakroc and worked with the RZA. I'm still hoping another Blakroc album is in the works, but we shall see. Now the song "The Baddest Man Alive" will be on the soundtrack to RZA's upcoming film The Man with the Iron Fists. The song blends that blues sound The Black Keys became known for, with some tough Wu-Tang style rap thrown in, but it is a strong track. Stream it below.
