In 2008, Grinnell's Jennifer Williams Brown won a major award from the American Musicological Society for her edition of Francesco Cavalli's 1651 opera La Calisto. Want to hear what it sounds like when performed using her discoveries? You're in luck! IPR will broadcast a recent performance from Simpson College Opera tonight at 7 PM and again Sunday October 25th at 4PM. Brown, who chairs Grinnell's music department and directs its Collegium Musicum, served as scholar-in-residence, dramaturg, musicologist, and coach for this production.
