Being labeled "the topless cellist" was a mixed blessing for one American artist of the avant-garde. Charlotte Moorman's occasional nudity in her performances attracted curiosity, but it also may have distracted from the pioneering work she brought to experimental art of the 1960s and ‘70s. A new exhibition looks at the bold life and legacy of this musician, performer and muse.

A show dedicated to the life of the barrier-breaking performance artist opens Saturday at Northwestern’s Block Museum.
