No Regerts, the recent (and hilariously titled) album from Chastity Belt, is a quietly brilliant and important document of feminism and sexual insight, disguised as remarkably surefooted indie rock. With lyrics that vacillate from the winking to the serious - though always trenchantly well-observed - Chastity Belt build solid, simple punk-leaning songs that serves the ideas on the table, without the music or the words ever coming into conflict. Musically, no boundaries are necessarily being pushed, but everything comes across energetic and effortless. Their most thrilling moment comes in "James Dean," with its bracing stop-start dynamics, and wailing proclamations like, "You're a slut! I'm a whore! We've fucked everyone before!" There's a real effort, all through No Regerts, to call hypocrites out on their bullshit, and to hopefully move toward a more even playing field.
