Rojai Trawick, known as Mista Grimm, is a rapper formerly signed to Epic Records' sub-label, 550 Music. Grimm’s first release was the 1993 single “Indo Smoke” featuring Warren G and Nate Dogg, included on the Poetic Justice soundtrack.

The following year, he released a single entitled “Situation: Grimm,” which appeared on the Higher Learning soundtrack. Grimm completed his debut album, Things are Looking Grimm that was originally set to be released during the summer of 1995, however after the album’s lead single, “Steady Dippen” failed to make an impact, the album was shelved.

Little has been heard of Mista Grimm subsequently aside from a song called “Grow Room” on DJ Pooh’s 1997 album Bad Newz Travels Fast, appearances on T-Bone’s albums Tha Hoodlum’s Testimony (1995) and GospelAlphaMegaFunkyBoogieDiscoMusic (2002), and an appearance on Warren G’s 2001 album The Return of the Regulator.
