David Adjmi’s intimately epic behind-the-music drama Stereophonic has now moved to Broadway after a hit fall run at Playwrights Horizons. At the smaller venue, the audience felt almost immersed in the room where the show takes place: a wood-paneled 1970s recording studio—decked out by set designer David Zinn as a plush vision of brown, orange, mustard, sage and rust—where a rock band is trying to perfect what could be its definitive album. Some fans of the play have wondered if it could work as well on a larger stage,but that question has a happy answer: Daniel Aukin’s superb production navigates the change without missing a beat. The jam has been preserved.
