The supergroup SuperHeavy, featuring Mick Jagger, Eurythmics founder Dave Stewart, singer Joss Stone, composer A.R. Rahman and reggae artist Damian Marley will release their debut album this September.

Mick Jagger and Dave Stewart co-produced the album, which was recorded in France, Cyprus, Miami and India. Most of the tracks were laid down over three weeks in Los Angeles earlier this year. The band wrote 22 songs in their first six days together. The first single is titled “Miracle Worker” and the band will be releasing a video for the track.

The connection between the band members starts with Jagger and Stewart. It goes back to their collaborations on the 2004 soundtrack to the film “Alfie”. Both wanted to bring in a Jamaican musician and Marley entered the picture with his rhythm section, bassist and composer Shiah Coore and drummer Courtney Diedrick. They met Rahman while recording in Los Angeles. Stewart produced Stone’s last album, thus the connection there.

According to the band’s bio, SuperHeavy came together after Jagger and Stewart wondered what a band of musicians from different genres would sound like. Jagger had his doubts it would come together. One of the first on the album is Jagger singing in Urdu. He takes lead on Rahman’s song “Satyameva Jayate,” which translates to “the truth alone triumphs.”

“It’s different from anything else I’ve ever been involved in,” Jagger told Rolling Stone last month. “The music is very wide-ranging – from reggae to ballads to Indian songs in Urdu.”

“We didn’t know what the hell we were doing,” added Stewart. “We were just jamming and making a noise. It was like when a band first starts up in your garage. Sometimes Damien would kick it off and then Joss would sing something on top of it. We might have a 22 minute jam, and it would become a six minute song.”
