A three-hour epic, “Jerusalem” begins with a fairy singing the lovely poem set to music by Sir Hubert Parry, which is shattered by rock music blaring from the speakers atop Rooster’s home. From there we’re off on a harrowing but frequently hilarious ride, staged with compulsive energy by Ian Rickson in a setting by Ultz that combines nature in bloom and humanity in wreckage, lit with dappling realism by Mimi Jordan Sherin. We know it will not end well. It’s to Butterworth’s credit that we are left so conflicted by this meeting with a force of nature, in the best play of the season.
