The madrigals in this book, aptly titled by Monteverdi "Madrigals of War and Love," range from solo voice or duo with continuo to works for eight singers and strings. Concerto Italiano gives a magnificent performance: the opening of "Hor che'l ciel" is daringly slow and still, only to give way suddenly to the narrator's cries of torment; "Ardo, avvampo" proceeds from the thrilling chaos of fire alarms to an extraordinary hush as two tenors end the piece in unison. In the famous "Lamento della ninfa," the musicians have found a way to follow Monteverdi's instructions that the three men should sing in strict tempo ("following the hand"), while the solo soprano nymph sings her lament in freer time, "following the heart." The result is astonishing. --Matthew Westphal
