CAMBRIDGE -- Somewhere in "The Onion Cellar," with its crashingly gorgeous music, its poetic images of bottled tears and scrawled sorrows, and its sleekly decadent Weimar/Vegas milieu, there's a fascinating play trying to get out. If this collaboration between the American Repertory Theatre and the Dresden Dolls provides only glimpses of that potential work, it's enough to make us long to see it in a more coherent form.
As it is, it's a beautiful mess. In the Zero Arrow black box theater, wonderfully transformed into a nightclub setting complete with tables and a cash bar, the Dresden Dolls -- Amanda Palmer and Brian Viglione -- unleash a storm of clotted chords and pounding rhythms in an irresistible display of the physical energy and emotional intensity that have made them one of Boston's fastest-rising bands. Palmer's sinuous voice weaves hypnotically through her viscerally satisfying melodies, anchored and launched by her fierce work at the keyboard and Viglione's hyperkinetic drumming.
