Gotham Chamber Opera Steps Out will feature singers, musicians and composers associated with the company, in a downtown setting different from their usual appearances in the theater. The repertoire will combine works from the Baroque era to the present, juxtaposing genres from classical to alternative rock, from operatic chestnuts to contemporary art song. Special guests performing this evening include singers Jennifer Check, Maeve Höglund, Eve Gigliotti, Gennard Lombardozzi, and Benjamin LeClair from Gotham Chamber Opera’s roster; alternative rock band Miracles of Modern Science, whose members include Gotham’s assistant conductor Geoff McDonald; and composer and performer Gabriel Kahane, whose work “You left me, sweet” was commissioned by Gotham Chamber Opera.
