Sir Mick Jagger loved arguing with his new supergroup.
The Rolling Stones frontman collaborated with Joss Stone, Damian Marley, Eurythmics' Dave Stewart and Indian musician A.R. Rahman in new band SuperHeavy, and Mick enjoyed the camaraderie of working with the other musicians
He explained: "We were writing a lot of stuff and throwing it away. I would say, 'That's rubbish, another cliche Joss', and she'd say, 'Well you come up with something then!'
"Us four vocalists, we've never worked like that before. It's great because the whole burden is not on you, and that made it fun."
Each member had their own unique way of doing things, with Joss revealing Damian often preferred working on his own first.
She said: "Damian is kind of quiet but he has some brilliant ideas. He works on stuff at night. Sometimes he'll just go away and sit with the lyrics and bring something to it. His rhythm section brings so much. He has his own thing going in the next room so I pop in and out."
Mick doesn't think the music falls under any specific category but says it is accessible and the band would love to tour if the fans enjoy the recording.
He said: "It's a new kind of music, it's a new genre, one that cannot be placed but it's very approachable.
"If you're a Rolling Stones fan there's definitely stuff you can relate to. Other stuff that you can't relate to so much, maybe if you listen you'll enjoy it.
"We haven't planned to do a tour or anything, but if people really like it maybe we will. We'd love to get out and play some of it live.
"As soon as we started playing together in the studio it gelled, and all these different styles didn't seem to be a problem to make them fit together... I hope people will like it..."
The SuperHeavy album will be released in September
