We're used to interacting with music on a level that's so fast that we usually only hear the result, but don't see what's actually happening. Here a great video that looks at what happens in slow motion when you play a variety of instruments and vocals, centering around the guys in Metallica.
What you'll see is electric and acoustic guitars, vocal, electric and acoustic bass, slap bass, piano and drums at 2,000 to 5,000 frames per second. My favorite is the snare drum at the end.
This is very cool. Thanks to my buddy Jesse Siemanis for the heads up.
