Back by popular demand: Seattle's star- studded tribute to the velvet voice and lyrical suffering of Patsy Cline, whose greatest hits are performed by an effortlessly brilliant band of old-school country-rockers and a parade of "girl singers," including Kim Virant, Kristen Ward, Star Anna, and Rachel Flotard. Cline's classics are elegant agility courses for singers, and the ladies of Sweet Dreams all rise mightily to the occasion.
