M.C. RG was an early Christian M.C. coming up in Dallas as a friend and contemporary of D-Boy Rodriguez. RG and D-Boy collaborated on tracks until D-Boy was murdered in 1990. On RG's 1991 album Think, he utilizes samples from funk giants such as Stevie Wonder and James Brown on tracks like Movin' & Groovin' and Simple Groove, and uses his track Dedication to dedicate the whole album to D-Boy.
