Evidence

Foreman’s slapstick humor—exemplified by the spectacle of an angel whose wooden wings precluded his getting through a doorway—was subtle.

Foreman’s closing night coincided with the first performance of Yvonne Rainer’s ambitious, chastely minimal mixed-media extravaganza The Mind Is a Muscle at the Anderson Theater on lower Second Avenue. — J.
