Speaking to USA Today, Stewart described how he and Jagger first invited Joss Stone, Damian Marley and Indian musician-and-producer A.R. Rahman together for what would become SuperHeavy, and that Jagger soon came to wonder what they were getting themselves in for.
“I said, ‘Hey, look, we’re going to try this experiment’,” Stewart remarked. “Everyone turned up without knowing what it was. Mick said, ‘This is mad. We haven’t written any songs.’ We started jamming, and it was amazing. It got to certain peaks where it was, whoa, this is happening.”
It also seems the pair are in disagreement over how long the new supergroup will last. “I know Dave is already talking about the next one,” Jagger explained. “As far as I’m concerned, it was a one-off thing. But we’ll see what happens.”
Recorded in Los Angeles, SuperHeavy’s self-titled debut will be released on September 20th.
