Founder and artistic director Thomas Crawford leads the American Classical Orchestra (ACO) in its second of four Manhattan performances this season with a special holiday program featuring members of the ACO Chorus on Thursday. The concert offers a selection of Italian works including the rediscovery of Antonio Bencini’s mislaid Christmas oratorio Gesù Nato from the shelves of the Vatican archives, as well as the retrieval of Antonio Gianettini’s Magnificat and five psalm settings. The program will begin with a brief presentation by Thomas Crawford describing the works and offering orchestral excerpts. Soloists are soprano Linda Tsatsanis, mezzo-soprano Kate Maroney, and tenor Alex Guerrero, with members of the American Classical Orchestra Chorus.
