Toronto-based band Pup is more than the labels many attribute to it. Although it is pop-punk at its core, Pup's chops are gnarly and full of grit. The band enlivens a sometimes tired genre with structurally intricate songs wrapped with an unhinged ferocity. Its exuberant ideas are delivered with an enthusiasm that is infectious, leaving listeners begging for more. With four-part gang vocals incorporated whenever possible, the band bursts from the seams with an unparalleled energy.

Pup plays with Taking Meds, ACK!, and California Cousins on Saturday, December 20, at the Bug Jar, 219 Monroe Avenue. 9 p.m. $10-$14. bugjar.com; puptheband.com.
