The Peabody Essex Museum is making noise, and it has nothing to do with those 70 zebra finches fluttering around in a white-walled gallery full of Gibson Les Pauls. No, the museum in Salem has announced the appointment of Sona Datta as its new curator of Indian and South Asian Art. The PhD is coming to PEM from the British Museum in London, where she specialized in the visual culture of South Asia. Also, the Peabody Essex Museum’s first composer in residence, the precocious Matthew Aucoin
, will perform “Words and Music” at PEM on March 7 and 8. (The program juxtaposing music and words in forms that include instrumental music and recited poetry will feature two world premieres by Aucoin, and performances by violinist Keir GoGwilt and visual artist Nick Pope.) A 2012 Harvard grad and the son of Globe theater critic Don Aucoin, Matthew Aucoin is the youngest assistant conductor in the history of New York’s Metropolitan Opera and is currently composing an opera commissioned by the American Repertory Theater.
