Stephen Immerwahr is an American musician best known as a founding member of **Codeine**, the influential slowcore band that emerged from the 1990s New York underground. As bassist and vocalist, Immerwahr helped define the band's minimalist aesthetic and introspective sound, contributing to their landmark releases including the critically acclaimed debut *Frigid Spring* (1992) and *The White Birch* (1994).
Though Codeine's primary output sits outside pure electronic music, the band's sparse, atmospheric approach and emphasis on restraint and space has influenced countless producers working in ambient, post-rock, and experimental electronic genres. Immerwahr's work demonstrates how traditional instrumentation and unconventional song structures can intersect with electronic music sensibilities, making Codeine a touchstone for artists exploring the intersection of indie and experimental sound design.
