If the generally liberal New York theater crowd has gotten a little tired of David Mamet, who with his acerbic wit and pugilistic mien now espouses mostly conservative views, it need not worry. There is another Jewish playwright with an equally dark and comic wit who is just breaking through. He is David Bar Katz, author of “The Atmosphere of Memory,” a play about a highly dysfunctional family, and he is one of the most watched mid-career playwrights in New York City.

He was not a practicing Jew, but Allen Ginsberg’s poetry was deeply religious in its mystical energies, shimmering visions and profound longings for transcendence. Nowhere is this more apparent than in “Kaddish,” Ginsberg’s incantatory, surrealistic elegy for his mother, written in 1959. Now comes “Kaddish (or The Key in the Window)” as a one-man play starring Donnie Mather in a new production in the East Village.
