James Matthew Seven is a Los Angeles–based producer, songwriter, guitarist, DJ, and lifelong record collector whose work moves fluidly across punk, hardcore, rock n roll, disco, soul, psychedelia, and beyond. Known for his adaptability and instinctive musicality, Seven brings a rare blend of authenticity, depth, and genre literacy to every project he undertakes.

Born in Toronto, Canada, Seven’s career began in the underground punk and hardcore scenes. At just 16, he co-founded the influential hardcore band No Warning, quickly becoming a defining force in the early 2000s movement. The band’s 2002 release Ill Blood (Bridge 9 Records) is widely regarded as a genre classic, followed by extensive international touring alongside acts such as Cro-Mags, Agnostic Front, Madball, Hatebreed, and American Nightmare.

As No Warning’s profile expanded, the band signed to Warner Bros./Machine Shop Records, releasing Suffer Survive in 2004. During this period, Seven recorded at legendary studios including Sound City and Sunset Sound and toured globally with major artists such as Linkin Park, Korn, Snoop Dogg, and Ghostface Killah. These experiences provided a foundation in high-level songwriting, production, and large-scale touring that continues to inform his work today.
