Ha... that's a nice problem to have! The particular mass that I embedded is much more than the single Credo that I featured, so make sure to collect it all! Zelenka is one of those lesser known composers from the Baroque era... strange harmonies, and some fiendishly difficult writing. He is better known to Czech audiences and double reed players (he wrote a lot of chamber music for them!).

I'll have a nice post with some great music by Buxtehude going up some time this week. Just editing it, and will probably put it up in the middle of the week.
