A great chamber music album of Benjamin Britten's music, esp if you like solo oboe! Not easy to find solo oboe recordings, but oboe is one of the most difficult instruments to reproduce correctly, a real challenge for playback system. You'll hear your midrange flaws easily, if you know what oboe supposed to sound like. Close miked, great tone.
Prazak is an awesome string quartet. Try their Beethoven Quartet cycle!
This one's on Tidal.
