From Warmowski, this priceless Van Halen train wreck, summed up here:
So what happens when you’re Van Halen, the last song in your set list is the million-seller “Jump” with its synthesizer-keyboard opening…and the recording you’re using to play back the synth is accidentally run at 48K instead of 44.1K?
Ouch. If you're wondering what the fuss is about, you can really hear it at about the 1:50 mark, and again at 3:00. It makes Stockhausen sound like Schubert.
