Anthrax are grateful to Metallica for giving them a "kick up the a-s" which helped them stay on the ball.
Being part of the Big 4 lineup alongside the best thrash metal bands in history gave them the confidence to make their album "Worship Music" amazing - and it paid off.
"Metallica's the biggest band in the world. To be on stage with them, let alone the Big 4, was huge for us. It put us back in the limelight, in front of this whole new fanbase," said bassist Frank Bello. "To see 14-year-old kids coming up, saying they love this record, they grew on my bass playing from their father - I love that. That's what it's about."
Speaking about their critically acclaimed 2011 album "Worship Music", Bello said their hard work paid off: "You've gotta come up with the goods. Nobody cares if you don't come up with the goods. We knew we had something special, It all worked. It was the perfect storm."
Meanwhile, it has been revealed that Slipknot frontman Corey Taylor almost stepped in on vocals for Anthrax, but was blocked by his label.
Anthrax had asked Taylor before singer Joey Belladonna returned to the band. "When I was all set to fly to Chicago and work with Anthrax, the label told me they wouldn't let me do it," said Taylor (via Classic Rock). "At first I was really mad about it but I let it go after a while."
