how about the climax of ondine , infact the whole of it , but specially the climax, it sure gives me the chills, and well i think i should say whole of gaspard de la nuit.
prokofiev's toccata and ravels toccata, give me the chills at the very thought of how can one ever play them, hehe, specially the ending of ravel's toccata ( not many pianists have done a good job there, i have heard so many great pianists, including gieseking, francois, and perlamuter ( who was also known for his debussy and ravel) completely mess up that ending of ravel s toccata) ) .
i get those chills in ravels piano concerto s as well, both of 'em , and that section of trills in the first movement of piano concerto in G, wow, it sends shivers down my spine.
prokofievs piano concertos, do the same .
i ll be back with more pieces when i can think of them.
