Well, just in case I'm not too late, and without worrying whether these are really my four very favorite recordings:
Stravinsky, L'oiseau de feu (complete) / Rattle, CBSO
Shostakovich, Symphony № 7 Leningrad / Ančerl, Cz Phil
Debussy, Prélude à l'après-midi d'un faune, Jeux, Images pour orchestre, Danses sacrée et profane / Baudo, Cz Phil
Tchaikovsky, Pf Trio in a minor, Opus 50 / Shostakovich, Pf Trio № 2 in e minor, Opus 67 / Martha Argerich, Gidon Kremer, Mischa Maisky
