When a radio interviewer asked deadmau5 about his disrespect for DJing as an art form, deadmau5 said he didn't know any virtuoso mixer players.
But anybody who knows anything about dub music knows that dub is all about virtuoso mixer players.
Turntablism is also all about virtuoso mixer players.
If you don't know of any virtuoso mixer players, then you don't know about Underworld - one of the greatest electronic acts of all time - and you don't know about dub or turntablism - two entire genres which have both shaped electronic music.
deadmau5 is an interesting producer and his live shows have tremendous style. But he talks a lot of shit, and he doesn't always know what he's talking about.
