Unlike other screamo acts, you can see brains when These Arms Are Snakes flip their lids. Stupid name notwithstanding, the Seattle threesome freak out thoughtfully, expounding on the lives of underpaid single mothers (“Angela’s Secret”) and “postmodern pigeons” (“Greetings From the Great North Woods”) between Goth, keyboard-caressed breakdowns. “Angela’s Secret” opens with a brawny synth line and Steve Snere’s ghostly yowl, then flares into overdriven guitar licks and (what else?) unhinged screaming. At eight minutes, the surprisingly fleet “Gadget Arms” evokes classic prog, while “La Stanza Bianca” has a post-punk swagger — gently profiling residents of a mental ward. The band’s got heart, too.
