On their debut full-length, Western Massachusetts’ Speedy Ortiz manages a bit of magic by conjuring the spirits of classic American indie rock, while twisting those ghosts into new shapes. It’s easy to hear the influences of Helium, Jawbox, and Chavez on this album, as well as nods to their contemporaries including Grass is Green, Pile, and Roomrunner. Sweet vocal harmonies run up against gnarly distortion, aided by basic, chunky bass parts and heavy, fill-laden drums.
