I don't listen to a ton of classical, but these would have to be on my short list:
Glenn Gould "Goldberg Variations" 1981 recording.
Barber's Violin Concerto, Gil Shaham recording.
In 27 Pieces: The Hilary Hahn Encores
Holst's The Planets: Montreal SO/Dutoit recording.
Beethoven's 9th: New York Philharmonic/Bernstein
