Joel Zimmerman also known as "Dead Mouse" is a house/trance electronic music producer who has been producing music since around 2005. He is one of the few DJ's who still popularizes and produces non-vocal melodic trance type songs and is most widely recognized for his trademark large light up mouse head that he wears on stage at shows. Some of his most popular main stream titles include vocals featuring other artists such as "Ghosts 'n Stuff ft. Rob Swire" and "I Remember ft. Kaskade". Deadmau5 has yet to win a grammy despite his five nominations but still has hope due to his young age of 32.
