Greta Gertler and the Extroverts, Edible Restaurant. Fresh, quirky indie pop by a singer-pianist with the bicontinental sensibility of an Aussie in New York, accompanied by a deliciously rough-hewn backup band whose deep-throated tuba and Salvation Army-style drums add a touch of Kurt Weill to the recipe. Check out “If Bob Was God” for a taste of Gertler’s smart songwriting (TT).
