Both CDs in this set contain pieces by R. Strauss or his father that aren't heard very often, at least in my experience. I found the music and all the performances on these 2 CDs to be very good and enjoyable to listen to, not only because they are well-played, but because before listening to them I'd heard these pieces very rarely if at all, and they are refreshingly new to my ears. I also like the variety of solo instruments featured.
