Brooklyn’s Peaer hits their stride on new single “Don’t,” utilizing patent stumbling math rock rhythms alongside major-minor chord modulations to create a track that is as engaging as it is disorienting. Regardless of vocalist/guitarist Peter Katz’s biting, occasionally sardonic lyrics (“why do you treat others like objects? / man, i’d hate to see how you treat objects”), there’s an inherent playfulness to Peaer’s craft, due in large part to the band’s tight instrumental synergy, their ability to interweave guitar, drums, and vox in ways unexpected and impressive. Better yet, Katz’s nonchalant vocal delivery occurring the midst of their well-choreographed performance endows “Don’t” with an effortlessly cool atmosphere. It promises more experimentation on forthcoming LP A Healthy Earth, out August 16th on Tiny Engines; listen below, and catch them at Elsewhere on September 27th. -Connor Beckett McInerney
