Opera review: David Lang’s “The Difficulty of Crossing a Field” given Southern California premiere by Long Beach Opera by Mark Swed Los Angeles Times June 16, 2011 Long Beach Opera on Wednesday night presented the Southern California premiere of David Lang’s opera “The Difficulty of Crossing a Field” at Terrace Theater.
