“Black Sabbath just released another album and that’s got big riffs on it as well. Iommi is a favourite of mine, for sure. There are just so many riffs from him.
"I like Paranoid, of course but then everyone will say Paranoid. The first riffs that you learn on guitar are Smoke On The Water and Paranoid. Iron Man is really, really good.
"I like a lot of Black Sabbath. Iommi was another innovator, no one had done that sound and look at how many bands it has influenced. You wouldn’t have had Metallica if you’d not had Black Sabbath.
"And then you wouldn’t have had Aerosmith if you hadn’t had the Rolling Stones. That’s just the way that rock ‘n’ roll works. That’s what I love about rock ‘n’ roll and I think Mick Jagger said it best when he said, ‘It’s only rock ‘n’ roll, but I like it.’”
