In the video below from Rolling Stone, Anthrax's Scott Ian recalls how the Big Four bands of thrash, which also include Metallica, Megadeth and Slayer, united for the first time ever.

It's been six years since the four biggest thrash-metal bands – Metallica, Megadeth, Slayer and Anthrax – embarked on what they dubbed the "Big Four" tour, but the memories are still fresh for Scott Ian. In the latest installment of Rolling Stone's "Had to Be There" series, the Anthrax guitarist recalls the feeling of sharing a stage for the first time with musicians he'd cut his teeth alongside and how he wished it had lasted longer.
