Potty Mouth has their debut EP up for preorder and Cherry Picking is probably the best example of how you could think these girls are straight out of the 90's. All their songs have this inspiration and i am still not 100% decided if some of them have too much inspiration. Anyways their first EP is up for pre-order and I think as time goes on they have the opportunity to develop into their own. Just look at the Black Keys first few albums (not saying the first few black keys albums are bad). Potty Mouth is definitely worth your time now, so have a listen :).
