All pop punk should grow up to be as smart as the Thermals. The Portland trio's 2006 album called The Body, the Blood, the Machine is a brutal song cycle about a near-future theocratic America. It's also an energetic punk-rock masterpiece, each song a short, sweet blast of overdriven guitars and restless rhythm. Arthur & Yu's In Camera couldn't be more different— a relaxed collection of hazy, homemade acoustic pop with slight traces of sweet '60s psychedelia. And Coconut Coolouts will party your ass under the table. (Neumo's, 925 E Pike St, 709-9467. 8 pm, $12, all ages.)
