Martin McCurtis, who produces, raps, and writes under the name Helluva, made a name for himself after supplying the epic swirl of orchestral strings and stirring piano for Tee Grizzley’s 2016 hit “First Day Out.” The Detroit-based producer parlayed that success into superstardom, supplying the smooth, club-ready beat on 42 Dugg’s 2019 standout cut “Dog Food” and the party-ready canvas for Megan Thee Stallion’s 2020 smash “B.I.T.C.H.”
