the French modernist master Olivier Messiaen, who died in 1992 at 83, was truly an original. No other music sounds quite like his, with its mystical allure, ecstatic energy and elusive harmonic language, grounded yet ethereal. Rhythmically his pieces slip suddenly from timeless contemplation to riotous agitation then back again, sometimes by the measure. In the introduction to his 1985 book on Messiaen the critic Paul Griffiths calls him “the first great composer whose works exist entirely after, and to a large degree apart from, the great Western tradition.
