Sometimes music is alchemy. Micah Davis, 26,known professionally as Masego, is a Jamaican-born American singer, sax player and all-around musician who fuses trap, house and jazz. His latest release Big Girls, from his debut album Lady Lady is “an ode to all the women in his life.” Masego’s previous efforts leaned further towards the trappy end of his sound, but this cut is more commercial and positive.
