Index For Working Musik is a London-based five-piece band known for their "downbeat neo-psychedelia" and post-punk sound. Formed in 2019 by Max Oscarnold and Nathalia Bruno, the group's music often features poetic lyrics, degraded electronics, and noisy, metronomic guitar work. They are known for a "collaborative, often chaotic" approach that fuses domestic recordings with avant-garde sound manipulation. Critics frequently compare their sound to artists like The Velvet Underground, Syd Barrett-era Pink Floyd, and My Bloody Valentine.
