The EDM-violin sensation aims for pop stardom on her third album. Lindsey Stirling has always been an anomaly; she found fame on YouTube and deals in a niche blend of classical-dubstep meets Celtic rock. But Brave Enough has more pop hooks, fewer bass wobbles, and guests like Rivers Cuomo, Lecrae, and Christina Perri. It’s her most polished LP yet, but longtime fans can rest easy. She hasn’t lost an ounce of her quirky charm.
