RJMrLA

In 2013, RJMrLA eleased his debut mixtape O.M.M.I.O (which stands for On My Mama I'm On). The mixtape was hosted and largely produced by DJ Mustard. The first song from this mixtape, "Ride Wit Me" was included and released, as the single. RJMLrA then appeared on the songs; "Thank God (Interlude)" and "When I Was Gone" from YG's debut album, My Krazy Life (2014). In July 2014, RJrMLA released his second mixtape Takin Niggas Beats, featuring local rappers; Shoota300, JaywhiteT, and Vince Staples (on a contrary to his first mixtape). Unfortunately disagreements between them erupted, which led to RJMrLA dropping their names from the project entirely. The beats on this mixtape were solely from made-up beats from the other rappers that were remixed by RJMrLA. On the same year, DJ Mustard released his debut album 10 Summers, where RJMrLA appeared on the tracks; including "Low Low", "Throw Your Hood Up" and "No Reason".[4]
