Manfred is the quintessential Byronic hero, a romantic superman who endures unimaginable suffering and mysterious guilt in connection with the death of his beloved.

When conductor Sir Thomas Beecham resurrected Schumann’s incidental music for Byron’s dramatic poem, it was an act of total reimagination.
