Theotokos is the living embodiment of a baroque church ensemble. In residence at St. Mary's Church on Grand Street on the lower east side of NYC, every week a new cantata is composed and performed by the group, based on and tightly linked with the liturgical readings assigned to that date. In addition, theologically relevant baroque and pre-baroque music is regularly performed, ranging from Palestrina to Telemann, early American church music, and beyond. Theotokos also runs a Gregorian Chant club, open to all, which regularly meets to chant mass and the divine office. In 2021 Theotokos began a fruitful collaboration with the Juilliard School Historical Performance program. Other guest performers have included Davóne Tines, Jean Rondeau, Myriam Rignol, Thomas Dunford, and William Christie.
