Another Four Seasons! Philip Glass wrote his American Four Seasons as a companion piece to the Vivaldi. The composer and the dedicatee/soloist (Robert McDuffie) couldn’t agree which season was which(??); so they compromised by leaving the decision up to the listener! The Prologue for solo violin and the three unaccompanied Songs that precede the 2nd, 3rd and 4th movements are in lieu of the usual cadenza:
Prologue
Movement 1
Song No. 1
Movement 2
Song No. 2
Movement 3
Song No. 3
Movement 4
