Mark Morris' 'Dido and Aeneas' an exuberant spin on ancient epic

Mark Morris' danced opera "Dido and Aeneas" is a tour de force of late 20th century artistic storytelling, a partial retelling of Virgil's 2,000-year-old epic poem "Aeneid" using Henry Purcell's 1689 musical composition. It is a riveting assemblage, one that smashes and rewrites stylistic boundaries.
