You should see the metal live shows. You cannot stay still when the music starts playing. Back in 2012 I went to see Lamb of God live in Bangalore. There was a huge line outside the venue and soundcheck was going on inside the premises. When the soundcheck started, everyone in the line instinctively started nodding.I always thought that excessive head nodding was just movie stereotype (like hexadecimal code for hacking) but this song brought my headphone to a really precarious position!
