Ever listen to a piece of classical music and think "man, this is pretty metal?" Well if you have, list the track here so we can all mosh in the opera pit.
 
Tracks that come to mind off the cuff:
Haydn: Cello Concerto №1, 1st movement: great grinding riffs
Shostakovich: String Quartet №10, 2nd movement: entire movement is heavy as hell
Bach: Harpsichord Concerto №1, 1st movement: it even shreds

I've banged my head to Prokofiev's Scythian Suite, 2nd movement: The Evil God and the Dance of the Pagan Monsters.

Ah yes, a good one. I could probably fill a list with Prokofiev and Shostakovich alone; wonder what was in the water back in ☭
