Timestamped to the suddenly "schneller" part in Mahler's 5th, 1st movement.
The first time I heard this, it seemed as though I was hearing the sound of controlled chaos. It was a damn mess, but there was a structure to the chaos that I couldn't put my finger on. I just didn't realize at the time that I literally wasn't able to comprehend what I was hearing, though of course, 20 years later, I listen to it in awe of its finely-tuned woven lines of orchestration, which Mahler was a fucking BEAST at.
