(quite nice historical venues!)
According to this post, it seems that they will be doing Litaniae Xaverianae (which I guess means ZWV 155) and also Il Diamante ZWV 177 (not mentioned what excerpts) - both great works which are rarely performed. This will be paired with the flute concerto in G major by Mozart, on Baroque period instruments. Details are sketchy at the moment, but worth checking out .
