It was a great evening, the Martha Graham Dance Company’s return to McCarter tonight. Gorgeous dancing, with three works of Martha’s (Errand into the Maze, Diversion of Angels, Cave of the Heart, and one new work (the compelling Lamentation Variations, shown above), and an unusually full house. Other than Bill Lockwood, who programs the series, nobody could have been more pleased than Marvin Preston. Preston, a turn-around management consultant, responded to a call to turn-around the Graham company in 2001, when it was in the throes of every kind of despair. Preston took the job knowing nothing about dance, stayed six years, and put the company back on his feet. Needless to say, he knows plenty about dance now. And he had every reason to be pleased and proud tonight.
