As half of New York duo City Morgue, rapper SosMula ("Sleezy") helped pioneer the trap-metal subgenre, providing a grittier, slicker counterpart to the raw energy of collaborator Zillakami. After finding global success in the late 2010s with albums like Vol. 1: Hell or High Water and Vol. 2: As Good as Dead, he ventured into solo work, issuing 13 Songs 2 Die 2 in 2021 and 2 High 2 Die in 2022.
