28 Grams

Oswaldo Contreras (born September 9, 1988) is an independent music producer and artist. Blending influences from multiple genres, he has crafted a distinct sound that stands out in both his compositions and productions. Professionally trained at SAE Institute in Los Angeles—and sharpened by years of real-world experience—Oswaldo has built a reputation as an artist steadily shaping his own unique style.

Over the years, he’s collaborated with talents such as Jahziah Anake, Tay Y.U.N.G, Digla Baby, Jaye Vataan, and many other rising artists. His discography includes the self-titled debut 28 Grams (2011), followed by PlayTime Dun (2016) and Bankroll Infiltration (2016). These releases earned him a small but loyal following, and with his upcoming projects, he aims to expand his reach and continue evolving as both an artist and producer.

In his own words:

“Thanks to everyone who listens to my music now, and everyone who will in the future. I hope my music lifts you when you’re down, helps you find calm when you’re angry, and always brings you back to a positive state of mind.”
