Mozart horn concertos (Dennis Brain as soloist)

Tchaikovsky's first piano concerto, and Rachmaninov's third. (Haven't found the perfect recording yet, but there are many of acceptable quality.)

Mahler's first symphony (probably with Karajan conducting)

Beethoven's first symphony

Any good organist playing Vidor's toccata, that thing by Vierne, JS Bach's toccata and fugue in D minor, and the passacaglia and fugue in C minor

Chopin preludes, waltzes and the 3rd ballade played by Ashkenazy

Vivaldi's "Dixit Dominus", ideally my bootleg recording of Mike Brewer with the National Youth Orchestra and Choir

Paganini's violin concerto

Gershwin's Rhapsody in Blue

Bruch's violin concerto (with Yehudi Menuhin as soloist)

Clues for listening: if you want background music stick on anything by Mozart. If you want to listen to something, put on the headphones and turn up the volume. There isn't much of a halfway house here.

HTH,
