Amongst the recordings of Madam Butterfy, the frst to represent the most modern and innovative side of the composer was this stereo recording from 1957 edited by Richar Moore for the American RCA It is indisputable that the fundamental interpretative approach was that of a great non- Italian conductor such as Erich Leinsdorf, who would later record all of Puccini's most important operas. Leinsdorf's interpretative modernity was magnifcently assisted by the participation of a lyric soprano like Anna Moffo and an impeccable tenor like Cesare Valletti. After many years, and also thanks to the splendid quality of the recording, the production of Butterfy remains among those of absolute reference.
