Bus Thirteen is a hip-hop production duo from Massachusetts comprised of producers onehitgags and Saber Fluids. The pair builds tracks rooted in boom bap's hardest traditions while threading in live instrumentation they perform themselves, layering bass guitar, keys, and brass over drums that hit like gospel on concrete.

Their catalog runs deep. The instrumental series Baby's First Bus Ride and Public Transit volumes established the duo's identity as architects of full sonic worlds, not just beat suppliers. Collaborative full-lengths with Reks[M>.A.G.A (Make Art Great Again)featuring cuts by Statik Selektah and DjDecks alongside guests Ras Kass, Planet Asia Termanology, and Shabaam Sahdeeq| Blue [Back Stabbers//Beautiful Dream, with cuts by 7L, and Blvff [Laughing In Traffic on MoGaMo Records) placed their production under some of underground rap's most demanding voices. Operating through MoGaMo Media, the duo handles production, mixing, mastering, and visual identity as a self-contained unit. Their latest project, Little Songs, Big Feelings, a collaboration with vocalist Leah Parrett featuring Benny The Butcher and Blu, arrives on Old Soul Music in 2026.
