Maybe this has come to the attention of others: in recent weeks a set of videos showing no fewer than 3 large scale works by Zelenka performed by the Daegeon Chamber Choir of South Korea have been posted on YT:
ZWV 21 (performance from 11/2014): https://www.youtube.com/playli…N1RuTWChtppRw0VwElCRSgchA
ZWV 19 (performance from 11/2015): https://www.youtube.com/playli…N1Rv0URDjHurMgwcXiXuEeZMm
ZWV 146 (performance from 10/2016): https://www.youtube.com/playli…N1RsL5Dmc8ABFVy9_BYEc9AJR
While the audio is not really of CD quality (would need some post-production) it is plain to see that these are exceptionally fine performances by really excellent players (Camerata Antiqua Seoul) and singers. Bearing in mind that these are some of Zelenka's most challenging works, the live performances are nearly note perfect and sometimes go at breakneck speed! I particularly like the ZWV 19 which I believe challenges the most recent existing recordings (Guttler, Bernius).
I hope we can look forward to more first rate Zelenka from this group, perhaps even a CD release.
