An ever-evolving musical concern, Portland’s Parenthetical Girls has been fortunate enough to drain blood (often literally) from a wealth of gifted collaborators over its unlikely eight-year existence. In celebration of this particularly knotty family tree, the group presents an evening of singular performances from (((GRRRLS))) past and present, concluding in a grand-scale, multi-disciplinary Parenthetical Girls performance. Featuring musical guests Golden Retriever, Classical Revolution PDX performing compositions by Jherek Bischoff, and a dance piece by choreographer Allie Hankins.
