He's actually not that talented. Ask anyone who really knows EDM and they'll tell you Deadmau5 is just a hack.. a copy/paste producer as he's always recycling the same sound of his over and over again. There's a reason why he hates Markus Schulz; the guy made a track called 'Very Exactly' under a pseudonym 'Deadrat6' which sound A LOT like any generic Deadmau5 track. When Joel Zimmerman found out about this during a gig in Toronto where BOTH of them were scheduled to play the same night, he threw a fit and refused to DJ if Markus was going to play as well.
Or how about that time when he produced samples for Fruity Loops as part of the stock package that came with the purchase of Fruity Loops. When some guy produced a track that used those loops LEGALLY, Joel threw a fit and demanded they stop and wanted to take further action (can't remember if he wanted to sue or something).
Joel Zimmerman is a diva... anyone that respects this guy either doesn't know how much of a douchebag he is simply has no integrity to be associated with such an egomaniac.
I don't think you're correct. It's not Markus Schulz, I think you're referring to Marcus Schossow.
