The short brick building that crouches at 33 Wooster Street is known to be a haunted house. How could it not be? For this is the location of the Performing Garage, home for nearly half a century to that most storied of experimental theater troupes in New York, the Wooster Group.

Performers who have acquired legendary status both among the exacting aesthetes of downtown Manhattan (Ron Vawter, Kate Valk) and on a more far-reaching level (Willem Dafoe, Spalding Gray) have acted, acted out, danced, got high, stripped down, camped out, built sets, trashed sets, fallen in and out of love, and recorded and videotaped one another exhaustively in the Garage’s small but exceedingly fertile space.

As for the shows themselves — usually overseen by the group’s ever-present, ever-elusive artistic director, Elizabeth LeCompte — they have always had a touch of the numinous. Bending, mixing and exploding genres and media, they dissolve the boundaries between high and low, hazy memory and hard facts, reality and its representations and, yes, the living and the dead.

Classic writers — Chekhov, Racine, Eugene O’Neill, Gertrude Stein — have been resurrected in conversation with a tumultuous, shape-shifting present for an astonishing 50 years. When I first arrived in New York in the late 1970s, these shows — which played to select audiences of 100 or less — were the ones that the coolest of experimental theatergoers swooned over, gossiped about and pretended to have seen even if they hadn’t. (I can’t be on lower Wooster Street today without walking into vaporous memories of Valk and Dafoe eerily channeling and transforming O’Neill in “The Hairy Ape,” or Valk splintering into multiple simulcast selves as a soulless, preternatural femme fatale in “House/Lights.”)

With its latest production, “Nayatt School Redux,” the group has trained its retrospective lens on itself — specifically on a play first staged at the Garage in 1978. (This reincarnation, which runs through Saturday, is completely sold out.) The result, its creators agree, is a kind of a séance.
