Who likes a Potty Mouth? That’s not just a line your mom says before grabbing the soap: it’s the name of one of the much buzzed about bands performing at Gigawatts Festival this Saturday. We rang up Abby Weems and Ally Einbinder to learn more about the punk-pop trio’s upcoming show and to find out if they’re ready to spring the follow-up to their well received last album, Hell Bent, released in 2013 by North Brooklyn’s own Old Flame Records. They were tight-lipped (rather than potty-mouthed) about that, but we did talk about their band crushes, translating life into lyrics, and mansplaining. Yes, they know how much that pedal costs and, yes, they know how to use it.
