The Anthem 'The dove descending' and 'Introitus' are real children of Stravinsky's later period. The one setting T S Eliot's text (in 1962) and the other a memorial homage to Eliot (1965), they both reveal Stravinsky's gift of textural clarity while remaining true to the serial language in which the pieces were written.
