And now for a Friday musical interlude, we bring you Van Halen caught on its comeback tour, except there was one big problem and it involved gadgets. What happens when you play back a prerecorded synthesizer track at 48K instead of the intended 44.1K? The whole track plays back a little bit faster and at a slightly higher pitch, that's what. A dissonant musical mess ensues, trapping the guitarist and bassist in an on-stage musical hell with nowhere to go.
