EDM beef! Deadmau5 has been critical of the big-time dance music world in the past, despite being very much a part of that world. And now his festival-headliner peer David Guetta has given him a whole lot of ammunition. As Billboard reports, video recently surfaced of the opening night of Guetta’s Fuck Me I’m Famous residency in Ibiza. At that show, Guetta pulled the douched-out one-two punch of including both live horses and dancers with Native American headdresses in his show. Deadmau5 might perform with a giant lit-up mouse mask on his head, but this was too much for him. And he (justifiably, I think) lashed the fuck out at Guetta on Twitter. Below, watch the offending video and read what Deadmau5 had to say about it.

for real… horses belong on a farm, not in a shitty overpriced nightclub to be subjected to a shitty overpaid DJ. @pacha

It’s amazing that that Coldplay remix was only the third-shittiest thing in that video.
