In this monumental early fresco by the composer of the “Resurrection” Symphony and Das Lied von der Erde, a youth who is the flower of chivalry vies with his vicious brother for the hand of a haughty queen who may not be worth having. The accomplished Aussie Simone Young, much in demand in operatic and symphonic capitals abroad, comes home for a rare encounter with a curiosity that would not leave its creator alone; he kept tinkering with it, in large ways and small, for some 20 years. —M.G.
