Mark Stewart (1960–2023) was a pioneering British musician best known as the frontman of The Pop Group, one of the most influential bands to emerge from the late 1970s post-punk era. Blending punk’s raw energy with dub, funk, and avant-garde experimentation, Stewart’s work challenged musical conventions and political complacency alike. Beyond The Pop Group, he pursued a bold solo career and collaborated with groundbreaking artists such as Adrian Sherwood and Tackhead, leaving an enduring legacy as a radical innovator who reshaped the sound and spirit of alternative music.
