This is the last week to see the photography of Roger Steffens and the Family Acid at Benrubi Gallery, in New York. Taken mainly in the sixties and seventies, Steffens’s self-consciously psychedelic pictures “imagine a different America, one of strange beauty and mystic truth,” as his son Devon put it. The photos are on display through August 26.
