Ian tells EMP Rock Invasion: "She's into metal. She's a genuine metalhead. So why not hear her sing - it doesn't even have to be an Anthrax song. I don't care. I would like to hear her sing in a metal way."

On which particular Anthrax track he'd like to hear Gaga perform, he says something off the band's latest album Worship Music would be ideal. He says: "Something off the album. In The End - that might be kind of cool to hear her sing that. I mean, she's got a great singing voice, so I just think it would be cool to hear her take on a metal song, because she's definitely got the chops for it."
