Before Mozart, there was Pergolesi. The 18th century couldn't get enough of the Neapolitan prodigy. He was the first great tragic musical wünderkind of the Enlightenment, prefiguring what Mozart would become for the 19th century. Like Mozart, Pergolesi died prematurely aged just 26. Like Mozart, Pergolesi was a musical simplifier and distiller, a divine and revolutionary sieve. Like Mozart, Pergolesi's popularity spawned an industry dedicated to mythologising his life and misattributing the music of contemporaries to him. Yet we celebrate Pergolesi's 300th anniversary this year, quite unlike we would Mozart's, with just one piece: the Stabat mater.
