This recording has an extraordinary pedigree. Per Accentus PR, it was in 2012 (probably still is) "the only audio-visual release of Bach's St. Matthew Passion performed by the choir for which it was written, in the St. Thomas Church, Leipzig, where the composer worked and is buried."
We haven't found a decent YT clip of this.
