This was quite something. Filmed (very nicely!) in the magnificent Baroque setting of St. Paul's Roman Catholic Church, Antwerp.
It was performed *within* the liturgy of the morning Easter Mass on 5th April, by the 'Sint-Paulus Camerata', conducted by (an *actual* Kapellmeister!) Ivo Venkov. As well as Zelenka's Mass, there are quite a few organ preludes (etc.) spread throughout. The church has an orchestral musical-liturgical tradition, which looks like a great project.
I really liked the long gap between the Gloria and the Credo, it really paces things out, and makes the return of the 'Amen' fugue even greater. I have yet to look into how the music for Mass at the Dresden Royal Catholic chapel would have been laid out, but this gives a tincy glimpse into the atmosphere created. For the first time, properly, I realised how the music can fit perfectly with the various feelings invoked by the Mass. In particular, how the drawn out melismatic arias allow time for personal reflection, and the choruses catharsis and jubilation. I hope the congregants of the Dresden chapel in the 1720s did not take the experience for granted!
Despite not knowing any Flemish, it was easy to follow for a Catholic like myself :). The coordination and organisation for this must have been considerably difficult - it may have been the cause of a slightly embarrassing failure of the Benedictus movement the first time round. It was pulled off beautifully in the end however 
.
At 1hr 14mins in, a person also stands at the lectern to read a bit about the Camerata group and Zelenka. They finish off the day with a great rendition of Handel's 'Alleluia' as well.
