Klaus Sperber (January 24, 1944 – August 6, 1983), known professionally as Klaus Nomi, was a German countertenor and baritone noted for his wide vocal range and an unusual, otherworldly stage persona. In the 1970s, Nomi immersed himself in the East Village art scene. He was known for his bizarre and visionary theatrical live performances, heavy make-up, unusual costumes, and a highly stylized signature hairdo that flaunted a receding hairline. His songs were equally unusual, ranging from synthesizer-laden interpretations of classical opera to post-punk covers of 1960s pop standards like Chubby Checker's "The Twist" and Lou Christie's "Lightnin' Strikes". Nomi was one of David Bowie's backing singers for a 1979 performance on Saturday Night Live.
