From Cardiff, England, the five-piece Crystalline have a collection of recordings that suggest they’ve got something worth developing. First off, frontwoman Eva Moullen brings an appealing quality and a powerful set of pipes to the mic. And her bandmates can indeed play, especially the guitarist. Most impressive is “Poison,” whose solid chorus hook is the group’s best. We like how Moullen’s voice powers-up from low to high, with a nice bed of synths beneath the guitar’s growling riffs. The record suffers, however, due to production and sound mix that do little to help it all gel. Same with “Mine to Break” and “Little Boy Lost.” One wonders what this group could be with a savvy producer at the helm.
