This 1994 Cantus Cölln recording on dhm features little-known motets for two choirs by Pachelbel, Johann Christoph Bach (1642-1703) and Johann Michael Bach (1648-1694), and the more modern motet, "Ich lasse dich nicht" BMV 159a, formerly attributed to J. Christoph Bach but apparently composed by J.S. Bach. The CD brochure includes the motet texts in the original German and Latin with English translations, and the English translation of Dr. Peter Wollny's program notes. All of the music on the disk was new to me, including the motet recently attributed to J.S. Bach. The latter, though short, is quite interesting. It begins in the dotted rhythm of an aria siciliana, with one choir echoing the other. This is followed by a fast second part, in which one choir sings a background chorale. In "Halt, was du hast", a much longer motet, J. Christoph Bach wove a complementary theme around the chorale "Jesu, meine Freude". In the second part of the motet, the second choir departs from the chorale text and echoes the first choir.
As for the recording: it's exceptional, as one might expect when the recording engineer is Dr. Thomas Gallia and the performers are Cantus Cölln, in this case featuring Johanna Koslowsky and Maria Cristina Kiehr, sopranos; Graham Pushee and Kai Wessel, countertenors; Gerd Türk, Wilfried Jochens, and Martin Post, tenors; Stephan Schreckenberger and Raimond Nolte, basses; Christoph Anselm Noll, organ; and of course Konrad Junghänel. The motets are performed one-to-a-part in accordance with the research by Joshua Rifkin and Andrew Parrott.
