The electronic chefs in Big Science don’t really have a recipe for their “Sound Soup.” Tyler Scouton, Aaron Molina, Tim Kaiser, Nate J. Mattson and Jake Larson bring their strange, homemade ingredients to their kitchen stage in boxes, laptops and keyboards. They plug everything in, mix it all together and let the sound boil over. The concoction is served up in a wash of beeps, buzzes, screeches and drones. It’s a hearty, stick-to-your-ears feast that has as much flavor as a beef stew made with a truck load of potatoes and every vegetable in the SuperOne produce section.
