HipHopDX Premiere: After meeting while on a football scholarships at Colgate University, Gerard and Ty — the California-based Hip Hop duo known as 13Rings — quickly became friends, and eventually started making music together. After spitting out tracks like “Dey Way,” “Grizzy” and “COLD,” the duo has returned with an enticing new video for “All I Know,” which finds them flossing masks and graphic art to conceal their faces. Directed by Jayeb Entertainment and produced by Gerard, it’s an ideal introduction to the two hardworking artists despite the mysterious delivery. Watch the video above.
