Sid Alcatraz & the Killjoys is the creative vision of Brennan Llewelyn, who writes, performs, and produces every track. The band’s sound fuses Jazz and Funk syncopation with the stylization of Glam Rock and Post-punk; delivering immersive soundscapes with vulnerable vocal performances.

Llewelyn employs a preliterate writing style, allowing ideas to flow organically without the constraints of traditional structure. Every recorded instrument is improvised, capturing a raw, spontaneous energy that defines the band’s unique sonic identity.

Drawing inspiration from Siouxsie and The Banshees, Cocteau Twins, and The Cure, as well as icons like David Bowie, Prince, and Iggy Pop; The Killjoys craft a sound that is both nostalgic and strikingly original.
