Reddit reviews Schubert: String Quintet in C, d. 956

With Schubert, oh yes I do! The Fischer-Dishkau/Demus recording of Winterreise is a real treasure. Even people who aren't keen on lieder may find it appealing:

Kleiber's rendition of the "Unfinished" symphony is the best I've heard:

And I love the Takacs Quartet's take on the 13th and 14th string quartets:

Finally, the Emerson Quartet playing with Rostropovich (what a team-up!) for the String Quintet:

As for Mahler you can't go wrong with Rattle's recording of the 2nd Symphony or Bernstein's recording of the 5th. Bernstein playing Rhapsody in Blue is terrific as well. Hope this helps :-)
