DJ Rhettmatic (born Nazareth Nirza) is a producer, DJ and member and part creator of Southern California's first turntable band, the Beat Junkies. Rhettmatic began his DJ career in 1983, with Double Platinum, a DJ group based out of Cerritos, CA.

His talent and musical expertise also extends into the realm of music production that helped him earn recognition and rewards. Rhettmatic highly acknowledges fellow Beat Junkie member, DJ Curse, as his leading mentor. As Curse shared his turntable exhibition, involving scratches and other DJ techniques, Rhettmatic's interest in DJing formed, allowing him to take hold of his musical passion. Rhettmatic claimed the titles of Disco Mix Club (DMC) West Coast Champion (1996) and International Turntablist Federation (ITF) 2x Team World Champion (1997/1998).
