Progressive house/minimal trance and techno producer and DJ, born on January 5, 1981 as Joel Zimmerman and raised in Ontario, Canada. He first released music in 2000 as Karma K, and adopted the alias Deadmau5 in 2005.
He established the label
Mau5trap Recordings in 2007.
The name Deadmau5 (pronounced "dead mouse") comes from an incident where a mouse crawled into Zimmerman's computer. "Dead Mouse" was too long for a website login name, so he abbreviated it to "deadmau5".
