Joel Thomas Zimmerman (born January 5, 1981), better known by his stage name deadmau5 (pronounced "dead mouse"), is a Canadian progressive, electro, and house producer based in Toronto. His tracks have been included in compilation albums such as In Search of Sunrise 6: Ibiza, MixMag's Tech-Trance-Electro-Madness (mixed by deadmau5 himself), and on Armin van Buuren's A State of Trance radio show. His debut album, Get Scraped, was released in 2006, followed by others in the next few years.
As well as his own solo releases, deadmau5 has worked alongside other DJs and producers, such as Kaskade, MC Flipside, Rob Swire of Pendulum, Skrillex, and Steve Duda under the BSOD alias. He is known for often performing in a titular costume head, which resembles a mouse head, that he originally created while learning to use a 3D program.
