Oftentimes, when you get a bunch of rock stars from different genres and generations together, gelling or fostering chemistry becomes difficult. Not so with Mick Jagger and his pals in SuperHeavy.

Matchups like this, pairing the Stones frontman with the Eurythmics' Dave Stewart and soul singer Joss Stone among others, that seem like good ideas on paper often fail in execution. Writing sessions can devolve and turn into aimless jam sessions.  Jagger says SuperHeavy stayed focused on songs. They were also interested in checking things like ego at the door, thank you very much.

"We were looking to do a record that didn't sound like anything we'd heard before, and we thought we'd do this musical mixture of people that would harmonize together yet bring things from musical places that we knew about and might have even dabbled in, people that specialize in different things and would bring different voices," Jagger told Spinner.

He continued, "So, [it was] people coming from different musical places but able to subsume their egos for a while and throw everything into the mix and hope something's gonna come out. We didn't know what was going to happen. We didn't know if we would get songs. We wanted to make songs; we weren't interested in jams."

Since Jagger and his bandmates knew that songcraft was the most crucial element of their coming together, things took a natural course. He admitted that the process was different for SuperHeavy than that of the Stones.

As he explains, "Well, songwriting is songwriting, you know what I mean? You can come at it from all different points of view. With the Stones, we do lots of different ways of songwriting. You've got the sort of 'hope for the best' songwriting, where you turn up and you've got nothing, and you've got like writing everything completely demoed and then laying it on people, so I'm used to writing in very, very different ways."

You can judge for yourself how the band's songwriting went by listening to the first two released SuperHeavy songs, 'Miracle Worker' and 'I Can't Take it No More.'
