Matthew “Slim da Reazon” Parham is a Los Angeles based voice actor, photographer, poet, and musician born from Cincinnati, Ohio. His interest in Black literature, spoken word, rock, hip-hop, and jazz blend to become a language and lifestyle Parham calls AfroGrungeTM. Duality, double consciousness, and the alternative Black experience are themes Parham explores across genre-blending visuals and performance mediums. Visually, this edgy style is replicated behind his lens through a photographic portrait approach, which relies heavily on darkness and light, black and white, and most often focuses on Black subjects or like-minded creatives.

Parham is also a sought-after voice actor, nominated for a Society of Voice Art and Sciences Award in 2022, the VOA Unicorn Award and two One Voice Awards in 2024, with a client list including Marvel, MTV, MGM, PBS, Nike, and DSW.

Matthew is most notably the Director of Operations for the National Association of Voice Actors (NAVA), where his advocacy includes lobbying on Capitol Hill and national panel appearances, while also serving as Community Liaison with the South Los Angeles arts gallery Range Gallery.

Since 2017, Parham has been the MC in a 15-piece jazz hip-hop ensemble called The Urban Renewal Project, with whom he has toured nationally in 100+ shows.

When he’s not serving the voice-over community with NAVA, voicing projects, performing poetry, or making music, Matthew is finalizing a photography certificate at UCLA.
