While me and my bro are rocking out at mayhem fest 09, we noticed some thundering and lightning from a distance. What made this a great moment is that it start to rain, thunder, and lightning over us while \Slayer was playing. This was a great moment because it happened when Slayer was playing raining blood. It was like they summoned it or something. It could've been better if it was blood instead of water. Slayer forever
