[lbsquat]

What about Beethoven 7th symphony mov 2? The buildup in the beginning is unsurpassed.

[parsifal]

Slow section of the Liszt sonata
Cadenza of ravel left hand concerto?

[cheetahman]

the multiple climaxes of 1812 overture sound great. can't believe none of them made the list. also, what is number 3, I can't find the start of it.
