Michala Petri’s version of Vivaldi’s Six Flute Concertos op. 10 with the Academy of Saint-Martin-In-The-Fields under its first fiddler Iona Brown was recorded in July 1980 – almost the prehistory of Vivaldi interpretation, seen 35 years later. And after all, yes, 1980 is almost exactly the middle point between the beginning of the great 20th century Vivaldi revival, heralded by Louis Kaufman’s ground-breaking recording of the Four Seasons on Concert Hall in 1948 (Vivaldi: Twelve Concertos, Op. 8), and today.
