I am probably the last person on this blog to write anything about heavy metal, but when I was told about this video, I had to put a post together.  Metal band Machine Head played what looked to be a packed house at the Town Ballroom this past Sunday, and during the show, invited a 13 year old guitar player named Anthony Potenza on stage to join them for their song "Aesthetics of Hate" after Potenza had flashed a sign to the band requesting to sit in for the song.  After lead singer Robb Flynn fit the teen with a guitar, Potenza  proceeded to kill it, acting like he belonged up on stage with their the band, going note for note, while taking the lead on solos as well.  A pretty cool moment for both the band and especially Potenza as the crowd completely ate it up.  Check out the video below.
