Formed in 2001, Boston band The Dresden Dolls fused alternative rock with a German cabaret style from the 1930s to create an act that's truly unconventional. This live performance from London's restored Roundhouse features circus performers, gymnasts and cabaret dancers as the group unleashes songs such as "Sex Changes," "Gravity," "Coin-Operated Boy," "Backstabber," and others. 134 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital 5.1, DTS 5.1; "making of" documentary; bonus footage.
