Arcade Fire frontman Win Butler may or may not have considered the size of the reaction he was going to get for praising “all the bands still playing actual instruments” during his own band’s set at Coachella this year. He’s definitely gotten one, however, especially from EDM apothecary deadmau5, and it continues on, weeks after the remark was made.

Joel Thomas Zimmerman, the man behind the mask of deadmau5, responded to Butler’s remark with a Twitter attack (below), but it did nothing in stopping Arcade Fire’s feelings on the matter. Instead, as the band played a show in St. Louis this Saturday, they flashed an image of the DJ’s well-known mouse head on one of their video projection masks while they performed their song “Normal Person.”

Here’s a quick look at the performance:

Here also is the Twitter rant deadmau5 went on, after Butler’s comment:

Who knows where this artist feud will end up next. In the meantime, Arcade Fire continue their Reflektor tour, having just wrapped a surprise show at the Roxy last Monday night, and it will soon take them to Glastonbury. Deadmau5 is doing much of the same, coming down from his set at last month’s Ultra Music Festival, then heading to the Pukkelpop fest in August.
