25 Evil Sounding Heavy Metal Guitar Riffs

This is a video of musician Andrea Boccarusso performing 25 menacing/evil sounding guitar riffs from songs. How evil were they? I got the goosebumps! And not just because I refuse to turn the heat on until October and it’s 52 degrees in here, but my girlfriend has like six sweatshirts on right now and is still complaining about the cold. I’d jokingly suggest maybe it’s her witch’s nips, but she actually does do magic and I’m honestly afraid of the spells she casts when I’m asleep.
