New Erections is about as close this San Diego flailcore four-piece has ever come to pop music. Of course, “close” is still pretty far away when your back-catalog is a bunch of bleating screeches, squealing guitars, math-spazzing, and blast-beaten percussion hiccups all squeezed into tangled fits shorter than your favorite ringtone. Nevertheless, the change is tough to ignore on New Erections, where bassist/vocalist Justin Pearson has turned his blood-curdling shriek into an unruly growl, and The Locust’s finally fit some mood swings and extended dynamic shifts into their characteristic 50-second freak-outs. Spazzcore growing up? Hardly. The Locust spreading its wings? For sure.
