Deadmau5

Canadian progressive house/minimal trance and techno producer, and DJ, born on January 5, 1981 as Joel Zimmerman and raised in Niagara Falls, Ontario. He first released music in 2000 as 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 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".
