There is a new disc of Trio Sonatas in the works this month:

Pasticcio Barocco
Label-Hérisson 005
ZELENKA Sonates N° 4,5 et 6 pour 2 hautbois, basson et continuo
David Walter et Hélène Gueuret Hautbois
Fany Maselli Basson
Mathieu Dupouy Clavecin
Esther Brayer Contrebasse
Rémi Cassaigne Théorbe

I believe they play on modern instruments.
This is available Feb 23 according to
I would assume they will record Sonatas 1-3 at some point as well.

Is it just me, or does it seem that France has become a hotbed for Zelenka appreciation?
