Pure chaos. What are your favorite hectic, agitated moments in classical music?

I adore when things get a little crazy in the concert hall. My favorite chaotic moments include:

Szymanowski Symphony No. 4, III (love those glissandos in the violins so much)

Shostakovich Symphony No. 9, III (love the blustering trumpet solo)

Mahler Symphony No. 5, I (about five minutes in when the solo trumpet explodes into that chromatic whirlwind) and ofc Mvt. II !!
