Robert Kowalski, Marek Zwiebel - Vivaldi - Concerto No.8 in A minor for two violins and strings, RV 522, Op. 3 'L'Estro Armonico' (Orchestra Perpetuum Mobile, Igor Longato)
This was the first classical piece I heard in class and it stayed in my head, loud and clear, for days. These two guys are definitely not a disappointment to that memory, by performance or by the music.
