Unforgettable classics: Heifetz playing Saint-Saëns Introduction & Rondo Capriccioso in the 1930s. Maria Callas declaiming Mori! Mori! Mori! in Tosca in the 1950s. And, and, and .. And also Patricia Petitbon singing Ah! mio cor, schernito sei! from Handel's Alcina in 2009. A lovely voice; incredible music; an interpretation at one with the notes; and George Frideric Händel's superb empathy with the outpourings of a spurned woman.
