Vito Acconci was a father of performance and video art.
“Vito Acconci: Where We Are Now (Who Are We Anyway?), 1976,” at MoMA PS1, is made up of nearly 60 short pieces.
Mr. Acconci’s most important work can seem more like legend than fact. This month he is having his first American survey in more than 30 years.
