“I have a house in Jamaica that I share with a friend of mine. It’s in the hills, but it’s surrounded by villages. The houses from below have these sort of sound systems, so you tend to hear music echoing around. One morning, I heard a DJ who sounded like what you might hear in the Middle East sometimes. I also heard this drum and bass from somewhere else. I thought, ‘Wow, it’s be great to get two or three people from different backgrounds and do something like this.’ But I didn’t want to eliminate rock music or blues.
“It developed from there. I called up Mick and chatted about it, and he said, ‘That sounds interesting.’ He and I thought about who might work well, and we came to the conclusion that Damian Marley sounded good. We knew we wanted a girl voice, and Joss Stone came to mind. She loves Jamaican music, and she can really go for it as a singer. And then I suggested A. R. Rahman, whom I’d known for about 12 years. I invited them all to meet up at a certain place, and everybody turned up. From there, we started jamming. Some of the songs on the album are almost the same as when we jammed them in the big room.
“Damian mentioned the term ‘super heavy,’ because I think Muhammad Ali used to say it. It kind of stuck. Mick and I investigated having the name. Nowadays you have to go through trademarks and stuff like that. We were just a bunch of people experimenting, but I guess some of the people at Henson Studios were like, ‘Holy shit! What’s going on in there?’
“It was a really fun vibe; there were no egos at all. Mick was very into hearing everybody’s ideas, and he had a lot of his own. ‘Hey, that’s great.’ ‘Oh, that’s cool. How about we do this?’ It was very much like he was a collaborator.”
