Having celebrated its 50th season in stellar form, “Gotham’s flagship early-music presenter” (the phrase is The New Yorker’s) embarks on its 51st with redoubled ambition. In the words of Bill Barclay, the organization’s unstoppable artistic director, here is “a new journey for absolutely everyone.” In seven concerts at Corpus Christi Church, in Morningside Heights, distinguished international soloists and ensembles celebrate the Jewish New Year (September 21); Diwali, India’s Festival of Lights (October 9); All Soul’s Day, marked by masses for the dead by Johanes Ockeghem and Pierre de la Rue (November 2); Christmas, with music of J.S. Bach (December 7); the birthday of Scotland’s beloved Robert Burns (January 26); St. Patrick’s Day with an early tribute to the Dublin career of Giusto Tenducci, a castrato superstar of the 1760s (March 15); and the Muslim holy day Eid al-Adha with string-and-percussion vibes from the shores of the Bosporus (May 31). Is that all? No, it is not. At St. John the Divine, Barclay and the vocal ensemble Gesualdo Six premiere Death of Gesualdo, enacting the princely composer’s notorious murder of his wife and her lover in tableaux vivants that carry the trigger warning “ghoulish” (February 13). And at the New York Society for Ethical Culture, the program O Jerusalem: Crossroad of Three Faiths takes listeners on a musical tour of the holy city’s ancient four quarters—Jewish, Christian, Arab, and Armenian/Byzantine (April 12). Several of these events will also be made available online. —Matthew Gurewitsch
