Geza Gedeon, (Born September 28, 1952) professionally known as Geza X was a personality in the Los Angeles punk scene in the late 1970s. Geza produced records for a number of early California punk bands including the Dead Kennedys, The Germs, Black Flag, The Avengers and The Weirdos. His productions of "Holiday in Cambodia" for the Dead Kennedys and "Lexicon Devil" for The Germs separated California's punk sound from others at the time with its eccentricity, humor and spunk, making Los Angeles very different from the scenes in New York or London. Record executive Howie Klein, then writing for BAM, a San Francisco music magazine, was quoted as saying "...Geza X is THE ONLY person to capture the West Coast's compelling power and urgency."

Geza also played guitar, sang, and dealt with most studio issues in his band Geza X and the Mommymen. He is credited as having pioneered the use of the headset microphones now ubiquitous in music. They released one official single and a full-length album You Goddam Kids! on the minor label Final Gear in 1982. The song "Isotope Soap" was also featured on Jello Biafra's Let Them Eat Jellybeans sampler via Alternative Tentacles, and "We Need More Power" appeared on Posh Boy's Rodney on the ROQ Volume Two. The "Power Pals" fan club was started after the release of the latter song. It was thought that if enough people joined this fan club they would conquer the impossible and obtain telekinetic powers to reshape history.
