Before subjecting myself to the mud, garbage, and debauchery in Grant Park for Lollapalooza this past weekend, I took in a vibrant and intimate set by Single Mothers at the Fireside Bowl. Today’s 12 O’Clock Track is the Canadian hardcore band’s “Christian Girls,” the video for which uses the bombastic and cathartic song as a soundtrack to footage of one of the band’s similarly bombastic and cathartic house shows.
