There are too many choices. Many pieces that people are listing are good choices even though they would not be my first choices.
I would add Beethoven string quartet in C sharp minor,
Bach, Brandenburg Concertos and some of his Cantatas
Wagner, Die Walkure
Schubert, Trios for Piano Trios
Carter, String Quartets, especially # 2
For jazz, I would add recordings by Fletcher Henderson, McKinney's Cotton Pickers, Duke Ellington, Bennie Moten, Mary Lou Williams, Thelonious Monk, and Teddy Wilson with Billie Holiday.
For Blues, I would start with recordings by Blind Blake.
