On "Evergreen," a song that falls both at the spiritual and literal center of Copacetic, the full-length debut from Chicago pop-punk quintet Knuckle Puck, singer Joe Taylor embraces the idea that it's a big world out there, "where there's so much more than we think there is to see."

On "Evergreen," a song that falls both at the spiritual and literal center of Copacetic, the full-length debut from Chicago pop-punk quintet Knuckle Puck, singer Joe Taylor embraces the idea that it's a big world out there, "where there's so much more than we think there is to see."

"I'll lead a life of firsts on foreign soils," he howls atop punchy guitar riffs and pummeling drums. "Somewhere that I can find the bones of a better man inside."

The Knuckle Puck bandmates, who first connected in south suburban Chicago in 2010, have traced this gradual maturation over a half-dozen EPs, evolving from bratty Warped Tour first timers with a penchant for catharsis-seeking songs about feeling trapped in place ("Stateside," "Stuck") to worldly 20-somethings whose music is finally beginning to reflect this broader point of view.

Pop-punk purists no longer, the bandmates now sound content to let a prettier side show, at times anyway, and Copacetic comes across as easily the most musically diverse effort in the crew's catalog. This emerging melodic side surfaces most cleanly on the album-closing "Untitled," a seven-plus minute epic where Taylor sings about "building his guard up to the clouds" even as the song threatens to reduce these long-established defenses to rubble.

Seaway, Light Years, No Dice and Dead Set Ready also perform.
