"No regrets!" Brian Hake sings on the title track of "Teeth Like Cities," the parentheses-closing EP from long-dormant indie rockers Kopaz. Later, a call and response ensues, with an ethereal chorus intoning, "Open up your eyes," and Hake answering, "Sit back; enjoy the ride."

"No regrets!" Brian Hake sings on the title track of "Teeth Like Cities," the parentheses-closing EP from long-dormant indie rockers Kopaz. Later, a call and response ensues, with an ethereal chorus intoning, "Open up your eyes," and Hake answering, "Sit back; enjoy the ride."

It's a well-adjusted worldview for a band that once seemed primed to take over the world. Kopaz had big ambitions during its early-'00s heyday, and if they didn't achieve the professional recognition they hoped for, the new EP shows they ascended to great artistic heights at least.

Recorded at home and at Relay Recording over the past five years, "Teeth Like Cities" is dense and intense but immensely approachable. An epic post-rock approach calls for everything from gauzy keyboard sounds to glitched-out mechanized beats to glockenspiel to a full arsenal of guitars.

Each ingredient funnels into a dusk-lit dream world bolstered by rich instrumental stretches, an ear for pop melody amidst the tumult and even some early emo influence that shows the genre need not be poisonous when deployed properly. It makes for a fine curtain call.

Kopaz will also unveil a B-sides compilation called "Vitras" Friday, when SPD GVNR joins them for the Rumba release show.
