Joel Thomas Zimmerman (born January 5, 1981), better known by his stage name deadmau5 (pronounced "dead mouse"), is a Canadian progressive-house music producer and performer from Toronto, Ontario.

The mouse-helmeted DJ has been collecting vast amounts of cheese despite performing half as many shows as some of his peers, thanks to nightly fees in excess of $200,000 at Hakkasan and other clubs and festivals around the world. He also cashes in on recorded music, his own label Mau5trap and massive merchandise licensing deals.
