Beautiful Classical Smaller Pieces, duo,trio,etc

I like "The Complete Mozart Divertimentos" NY Philomusica records, Disk 2.
I was driving home late, after a brutal day at work, and heard a track on the radio.
It was so beautiful and otherworldly that I felt like time stopped and I was dreaming.

The mendhelson octet!

All of the Baroque titles on the Harmonia Mundi label, if you find period instruments "beautiful".
