Query: A mystifying dud from Boulez

Pierre Boulez frequently returns to the repertoire that established him in the Seventies on the Columbia/Sony label. He made an acclaimed Symphonie fantastique back then, but this 1997 remake is mystifying. It's so inert, undernourished, and detached that one can't imagine the conductor had any interest in the performance. Yet every bar is under control, and the Cleveland Orch. plays suprbly, so boulez had something in mind. He isn't simply drifting. Did he want to bring out the classical side of an arch-romantic (Berlioz was a great admirer of Gluck)? If so, it was perverse to pick a work that demands color, atmosphere, and dramatic contrast, all the things utterly lacking here.
