This is a video of musician Rob Scallon (previously) performing Metallica’s ‘For Whom The Bell Tolls’ entirely with different forms of bells (does a Glockenspiel count?). You know, because why not? It was surprisingly relaxing, and didn’t make me nearly as anxious as listening to the original song. This was almost something I could fall asleep to, like a police siren or a baby crying.
Keep going for the video.
