Grimes’ weird-pop opus Art Angels was the best album of 2015, and her live performances during the ensuing Rhinestone Cowgirls tour were appropriately monumental, featuring costumed back-up dancers, lots of lasers, and a few special guests. What they didn’t feature, however, was too many Art Angels tracks, with most shows limiting the new material to “Venus Fly,” “REALiTi,” “Scream,” and “Kill V Maim.” But now she’s had a few months to figure out how to destroy these songs live, and that’s exactly what she’s doing. Grimes just kicked off her Acid Reign world tour in Seoul, South Korea last Saturday, and the fans in attendance witnessed the live debuts of lead single “Flesh Without Blood,” “Butterfly,” and an awesome cover of Schubert’s “Ave Maria,” which she has said is “one of my all time favourite songs.” Watch some footage from the show below; “Ave Maria” starts around 9:38 in the third video.
