Ice Eater takes pride in making music it considers unusual, but the five musicians who make up the post-prog-punk outfit are naturals in terms of pushing the sonic envelope. When describing their sound, the guys go back and forth between intentional mystery and direct comparisons to underground ’80s icon Joy Division and dance-rock innovators Talking Heads. Ice Eater’s sound is enigmatic at times, featuring elements of early disco, new wave, and post-punk. The band employs fast-tempo, punk rock elements with electronic additives like vintage drum pads and noise from the keyboards and effects. There are guitars, but they’re used nontraditionally — co-songwriter Zachary Edwards doesn’t just stand there and rock barre chords soaked in reverb. Rather, he uses his instrument to add texture, mostly in a mechanical way: creating grinding noises, plucking out bright, flickering melodies, or elongating small batches of notes into humming riffs. In fact, Ice Eater is a seriously mechanical-sounding band, due additionally to the stickwork of drummer and co-songwriter Wyatt Adams, who comes up with some inventive beats that in their drastic minimalism seem programmed. Ice Eater, though, produces every note organically, and the samples or loops that pop up here and there are original, non-computerized creations. “It’s all hardware, no software,” said keyboardist Jordan Kline. “There’s no computer, and there will never be a computer.” Their unique approach is as intriguing as their sound. Purposeful emptiness is greeted by echoing fresh rock. They bring intelligent writing and infectious vocals. They take the rock mold and break it. They take what is expected and prove they don’t care.
