Reddit reviews Mozart: Requiem KV 626

You're welcome! If any of those float your boat, maybe try also:

Mozart: Requiem, Schreier/Dresden

Beethoven: Violin Sonatas, Perlman/Ashkenazy

Schubert: Trout Quintet, Gilels/Amadeus Quartet

EDIT: Had a chance to really check out my library and would also add:

Berlioz: Requiem, Shaw/Atlanta(the Sanctus is stunning)

This CD of Steve Reich works

This set by the LaSalle Quartet, especially for the Schoenberg quartets

Louis Lortie's recording of Ravel's piano music

Chailly's recording of Mahler 4, primarily for the amazing pairing of Berg's 7 Early Songs

Cleveland Quartet doing Ravel and Debussy

Herreweghe conducting some Mozart wind music

This CD, especially for the Trois poemes de Mallarme, but it includes so much good music.

Lastly, this wonderful Gershwin collection.
