Flip a coin: if it’s heads, it’s love; if it’s tails, it’s torment. So was the theme of the evening’s program of seventeenth-century Italian music at the Morgan Library’s centennial concert last Thursday, as part of the Boston Early Music Festival’s 2024 series.

Headed by viola da gamba player Cristiano Contadin, the critically acclaimed Italian ensemble Opera Prima performs music of the Renaissance and Baroque on period instruments. American Soprano Amanda Forsythe joined Opera Prima in vividly imaginative interpretations of pieces by Monteverdi, Rossi, Strozzi, and Caccini, as well as other lesser-known composers of the period.
