Similarly to Avatar and Arch Enemy, Lamb of God was one of the first heavier bands I started to listen to. I love most of their songs for the musicality, though the edgy lyrics appealed to 15 year old me. Ghost Walking was one of the first of their songs I got obsessed with and I think a big part of that was the music video. It's a post-apocalyptic detective/adventure type story but with enough missing pieces that I couldn't help myself.
