Math Rosen is a Canadian electronic musician, composer, and occasional filmmaker.

He began making sounds at age 16 under the name Liar's Rosebush, a young talent in Ottawa’s burgeoning electronic music scene. After nearly a decade touring the noise community between Ontario, Quebec, and the U.S. Northeast, Math retired the Rosebush moniker and moved to the west coast to explore new creative challenges composing for film, theatre, dance, and even architecture.

Collaborations with filmmakers Andre Rehal and Illya Klymkiw (Toronto), visual artist Amir Aziz (Vancouver), and sound designer Antoine Bédard (Montreal) have broadened Math's sound into emotionally diverse territory, with a strong sense of storytelling at the heart of every composition.

With his fusion of bass music, sound art, and film score, Math has been genre-bending across the country in recent years, from Vancouver’s influential Low Indigo to Montreal’s legendary Mutek and Igloofest. Now residing in Toronto, he continues to surprise audiences with his high-energy live performances, filtering 21st century electronic music through a lifelong love affair with cinema, hip-hop, and 70s synth-rock.

Math moves at his own tempo, and brings a unique touch of drama to modern electronic music.
