Intimate playing from Sean Shibe, a deconstruction of Maria Callas’ vibrato and a deeply committed Boulez mid 20th-century masterpiece.

Of the two major composers to have had anniversaries in 2012, maybe it’s ironic that it has been the 150-year-old Claude Debussy, rather than the 100-year-old John Cage, who has largely been celebrated with silence.
