With a pack of backup musicians or just as a pair, Wellington's Anthony and Zachary Dewar have never fallen into old habits as a live folk-rock act. Can a pair of twins barely into their 20s really have old habits yet? The charismatic brothers tear through originals like "The Noise Boys" and "Sunshine" with considerable aplomb and even throw in an occasional Leonard Cohen cover. Sardonic banter, outlandish thrift-store fashion, and sweet harmonies dot every appearance — no two are alike. They're entertaining enough that Surfer Blood even brought them out on the road.
