Gary Jules (born March 19, 1969 as Gary Jules Aguirre, Jr.) is an American singer-songwriter, best known for his cover version of the Tears For Fears song "Mad World", which Gary recorded with friend Michael Andrews for the film Donnie Darko. It became the UK Christmas Number One single of 2003. Since then, Jules' version has been used on many American TV shows such as CSI: Crime Scene Investigation and House, as well as in a popular commercial for the critically acclaimed video game Gears of War.
Jules was involved with a wide variety of bands and other projects in the early days of his career including The Ivory Knights, Our Town Pansies, Woodenfish, Kofi, The Origin, Invisible, No Poetry, and Heroes and Heroin. His 2003 residency at the Los Angeles Hotel Café helped develop the location as a successful singer/songwriter venue.
