 The cantatas are also regularly performed on Sundays at Holy Trinity Lutheran Church, New York City, under the direction of the Cantor (currently Donald R. Meineke).While individual cantatas were recorded as early as the 1930s, a complete set was not attempted until the 1970s when Nikolaus Harnoncourt and Gustav Leonhardt began recording the Teldec set.This 20-year collaboration used historical instruments, with boys' choirs and boy soloists for most soprano and a few alto parts.
