Last summer Chicago’s My Dad released a split with Fat History Month, and the result was the band’s exploration of more avant-garde territory. That trend continues with its upcoming 7-inch for Naked Ally Records (and Black Lake Records in the U.K.), Mouth Bleeder. Lead by Dave Collis, the songs have added more experimental layers with every turn, and with the band’s current iteration featuring three drummers, the noise pulses unpredictably, making listeners worry about whether it will run off the rails or stay firmly on track for the song’s duration.
