Los Angeles native and West Coast staple RJmrLA is back with the highly anticipated fourth installment of his signature series, O.M.M.I.O. 4 — short for "On My Mama I'm On." Released June 27, 2025, through OMMIO/EMPIRE, the 16-track project clocks in at just under 45 minutes and serves as a full-circle moment, marking a decade since his breakout mixtape O.M.M.I.O. 2.
Production wise, RJ stays right in pocket with his signature West Coast sound; tapping in with producers Larry Jayy and Sorry Jaynari, especially on the single "Baby." Leading up to the album’s release, RJ dropped several singles including “Ramen” featuring Joe Moses & Nice, and “Hideem,” both setting the tone for a return to form.
O.M.M.I.O. 4 is a true reflection of RJ's evolution while staying rooted in LA's street culture. The project features a loaded roster of guest appearances, including Ty Dolla $ign ("2am"), DOM KENNEDY ("2 of Dem Ones"), BlueBucks Clan ("Better Than You"), Lefty Gunplay ("Hotline"), 310babii & Big Eph ("On God"), and Siete7x ("Streets").
While the game may be saturated with new talent, O.M.M.I.O. 4 is RJmrLA’s reminder that he’s still a key voice in LA’s ever-changing soundscape. The projects blends seasoned storytelling with new-school energy — bridging eras while remaining unmistakably authentic.
With O.M.M.I.O. 4, RJmrLA proves once again that he's not just from LA — he's for LA.
