I was listening to this earlier today! Got a fantastic live version too - "In the Heavens and in the Hells... they must wage war... Through chemical warfare!" Though I don't think it's Slayer's best tune - the Antichrist or Die By The Sword are better.
Though I'm amused by the vast amount of people calling machine-generated beats with a guy talking "songs." Because technically, they're not.
YouTube - Eruption Guitar Solo--Eddie Van Halen
Pure guitar masturbation.
Don't know if it's my favourite tune, but it's awesome!
