Arcade Fire mocks deadmau5 with mouse head during St. Louis concert

Last week, deadmau5 took to Twitter to respond to a comment Win Butler made about EDM during his Coachella set. Butler gave a shout-out to "all the bands still playing actual instruments," and essentially slammed electronically produced music.

"Arcade fire needs to settle down. some dudes devote their lives to instruments, others to electronic composition by cpu, dafuqs yer problem?" deadmau5 tweeted. "if i wanna watch real artists perform, id pick the opera before wasting a fucking minute of my life with arcade fire. #doyouevenscorebro?"

Keeping the feud alive, Arcade Fire brought out a mouse head on stage during their St. Louis show to mock the EDM superstar. During their performance of "Normal Person," deadmau5's head was displayed on an LCD screen, according to Consequence of Sound.

This isn't the first time Arcade Fire has used the stage to mock someone. Deadmau5 joins Rob Ford, George W. Bush, and Michele Bachmann on the band's list of "honorees."

No response yet from deadmau5, but we'll update you when or if he gives the Canadian band a piece of his mind again.
