If you're into Chopin, then I'd recommend this recording of his piano concertos: http://www.amazon.com/Tou-TsOng-Plays-Chopin-Concertos/dp/B00013D52G

If you're into Tchaikovsky, like myself, I'd also recommend this recording of the Violin Concerto: http://www.amazon.com/Violin-Concerto-Mutter/dp/B000001G7O/ref=sr_1_7?s=music&ie=UTF8&qid=1381471343&sr=1-7&keywords=mutter+karajan
