San Francisco has always kept the faith. While other local music scenes have moved away from the style, the tradition of guitar-based pop-rock bands and strong melodic songwriting continues by the Bay. The Bobbleheads are the latest carriers of the torch, and they’re doing it with total confidence and scrupulous attention to lyrical and sonic detail. Everything about the group – the ringing 12-string Rickenbacker guitars, the fleet but driving beats, the sweet multi-part vocal harmonies, the joy and love that radiates from their performances – feels effortlessly classic.
