A friend posted this on my facebook wall and I thought it was awesome, so I'm sharing it here. This is performed by the Michaelstein Telemann Chamber Orchestra in Saint Mary's Church, Muhlhausen Germany. Doing a bit of research on the church, it's 14th - 15th century, made from local limestone.
This cantata, "Gott ist mein Konig" (God is my King) was written to mark the Council Election, and premiered at this church in 1708.
The singing and playing are beautiful, and there's some great camera work highlighing the church. If you want to see more, part 2 is here.
