Director and star of the upcoming Kung-fu action film The Man with the Iron Fists‘ RZA has released his music contribution to the movies soundtrack. Featuring rock/blues duo The Black Keys for the single “Baddest Man Alive,” a song reminiscent of the very good BlakRoc project from 2009. The song is a perfect mix between swampy blues and hard hitting drums producing an epic tune. You would expect no less from the RZA. Listen below.
