Deadmau5

Canadian progressive house/minimal trance and techno producer, and DJ, born on January 5, 1981 as [a=Joel Zimmerman] and raised in Niagara Falls, Ontario. He first released music in 2000 as [a=Karma K] under various forums and adopted the famous alias Deadmau5 in 2005. (he also went by Pivoteffekt and fuckmylife)

He established the successful label [l=Mau5trap Recordings] in 2007.
As of 2025, "Create Music Group" has since acquired the label for 55 million.

The name Deadmau5 (pronounced "dead mouse") comes from an incident where a pet mouse crawled into Zimmerman's computer and died. "Dead Mouse" was too long for a website login name, so he abbreviated it to "deadmau5".
