X-Ray Spex were an English punk band from London that formed in 1976.
During their first incarnation (1976–79), X-Ray Spex were “deliberate underachievers” and only managed to release five singles and one album. Nevertheless, their first single, "Oh Bondage Up Yours!", is now acknowledged as a classic punk rock single and the album, Germfree Adolescents, is widely acclaimed as a classic album of the punk rock genre.
Initially, the band featured singer Poly Styrene (born Marianne Joan Elliott-Said) on vocals, Jak Airport (Jack Stafford) on guitars, Paul Dean on bass, Paul 'B. P.' Hurding on drums, and Lora Logic (born Susan Whitby) on saxophone.
