“Meat and blood are just two instruments that we use to make you question your preconceived notions of what music and art should be,” according to bandleader Tyler Scouton. Duluth’s pseudo-industrial weirdo noise band Bratwurst also includes Brennan Atchison, Jason Ratajek and Benny Tryon. Performances tend to include Scouton squeezing animal organs into mush with his hands then massaging his face and torso with gore. There’s also clanging and clacking metal. An angle grinder. Deep, enveloping, ominous, throbbing synthesizer. Guitars sometimes distorted past recognition. Shouting.
