Just scrolling through Youtube, and listening to music, and came across this concert when giving myself a Heavy metal fix (Born and bred on Black Sabbath and Led Zepplin)and came across this Pantera cocert in Chile.

Now be warned, not for yje faint hearted classical lovers, the music is pretty brutal, the crowd melds with it like nothing I have ever seen or heard before. It takes 3 minutes before the song starts, then something crazy and unbelievable happens between the band and the crowd, check it:
