A year ago I was a steadfast member of the rock-is-dead club. I’ve since changed my tune. Partly to support my friend and podcast partner Aaron Rhodes of Shuttlecock, I began making regular appearances as the weird old guy at underground punk rock and metal shows. The visceral rush of kids in mosh pits and defiantly amateurish musicianship at these small-scale performances renewed my passion for unpolished guitar-based rock. Prime Specimen, the new EP by the Lawrence, Kansas, noisemakers Jackoffs, consists of precisely the sort of savage sounds I admire. Allusions to 1970s-era no-wave and new-wave amid the apoplectic attack provide this old head with plenty of points of entry. Being proven wrong has rarely felt so good.
