Gaspare Spontini is a little-known Italian composer from the early 19th century who got his big break with a work he wrote for the Paris Opera in 1807, “La Vestale”. Earlier, we heard its overture conducted by Riccardo Muti, the current music director of the Chicago Symphony Orchestra, who has championed this Spontini opera. Maestro Muti made a complete recording of it with the opera company where he was principal conductor for 19 years. What is the name of this opera house in Milan?
