Kamermuziek van August Klughardt (1847-1902).
1. Strijkkwartet in F, opus 42.
Pleyel Quartett Köln.
2. Kwintet in C, opus 95.
Quintette Aquilon.
ah thanks. (The wind quintet Op.79 (misidentified by Concertzender... they're thinking of Foerster's Quintet Op.95, also on the CD...) is probably(?) the Aquilon Quintet performance from a Delta Classics CD from 2013; the Op.42 is probably the Avi-Music CD that couples the work with his G minor piano quintet -- as often the case when Concertzender doesn't explicitly say e.g. "Concertzender Live" or somesuch. But it's good to be able to hear them.
(Ah, right, I thought 95 looked a bit large. If Klughardt wrote any works with Op.# after 91, please send information (and evidence) and edit the list of his works over @ IMSLP- this would be nice for others besides me to know :) )
(This is Klughardt's first of two string quartets. You can btw hear another recording of his wind quintet over here... (http://imslp.org/wiki/Wind_Quintet,_Op.79_(Klughardt,_August)))
You are quite right, Eric.
Those Klughardt works are indeed available on both the Cavi-Music and MDG labels. Qobuz has both .
