On sophomore album Yes, Virginia . . . , Boston’s Amanda Palmer and Brian Viglione—aka The Dresden Dolls—have sharpened their piano and drum-based Weimar-cabaret-meets-goth-rock novelty act into a brilliantly realized vision. Palmer’s arch singing comes tempered with plenty of mordant humor, and the duo’s instrumental intensity imbues the arty songs with dark beauty and walloping force. The pair’s January 5th concert at the Vic Theatre should be a fine example of a band at the peak of its gloomy glory. Two Ton Boa and Meow Meow open.
