The Twitter beef between superstar DJs Diplo and Deadmau5 has been one of the most vicious and storied rivalries in dance music for years; these two simply do not like each other. They do, however, agree on at least one thing: The Las Vegas Electric Daisy Carnival — the massive dance festival that went down last weekend — is stupid. As Billboard points out, both of them have aired some grievances against the massive festival on Twitter.

For his part, Diplo’s complaint was fairly trivial: The main stage looks stupid.

edc main stage look likes Walt Disney present princess castle on crystal meth how do u guys play that thing & look at yourself in the mirror

Meanwhile, Deadmau5 — who, like Diplo, played Delaware’s Firefly Festival instead — had some pretty pointed things to say about an entire festival that only focuses on one genre of music:

*Exactly.* I had the whole state of Delaware to myself 🙂 and it was glorious. Fuck EDC. https://t.co/Dbn1eOyeVu

think about it… here are my options, go play EDC with every fucking DJ in the world, or corner my own fucking market. GEE, tough call.

"great idea, lets overconcentrate a music festival with the same shit again so we all blend into obscurity and promote the event instead"

"EDC" alone is a bigger brand than any fucking DJ who's ever played it. kinda sets the tone for where your place is there.

its not called competition when you have everyone doing the same thing. its called banality. https://t.co/0uVkV96auw

So it’s a festival with a stupid-looking stage that also reduces its performers to content-providing cogs. Got it.
