Toronto artist Mustafa (aka Mustafa the Poet, and Mustafa Ahmed) self-describes his music as folk. That said, his newest release, the serene “Air Forces,” certainly blends genres. The Jamie xx- and Frank Dukes-produced track ruminates on violence, faith, fame, friendship and more, and furthers these inquiries in the Kid. Studio-directed visual treatment. Altogether, the intensely emotional song sounds subtle and soothing—and emphasizes Mustafa’s originality.
