Mötley Crüe have released the full version of new song “The Dirt (Est. 1981).” The track is one of four new tunes the band contributed to the soundtrack of their upcoming biopic ‘The Dirt,’ based on their group biography The Dirt – Confessions Of The World’s Most Notorious Rock Band.

Bassist Nikki Sixx told Steve Jones (Sex Pistols) on his Jonesy’s Jukebox radio show of how the song came to be,

“We were in New Orleans. That’s where we filmed most of the movie. And we were flying back, and I was flying with Tommy [Lee drums]. We’re not a band anymore officially — we don’t tour. And I said, ‘Let’s write some music.’ And I didn’t think we would ever do anything again together besides this movie — we kind of called it a day. And I had about seven, eight songs I had been working on — not for Mötley Crüe. I was working with John 5 [Rob Zombie guitarist]. We were just writing music. So I had these ideas. And Tommy said he had a bunch of ideas. And Mick Mars [guitar] had some ideas. And we just started kind of putting them together. And we ended up with nine songs all called ‘The Dirt’. And by the time we figured out which ones we loved, we were down to three songs, and this song ended up being the one we chose for the first single. There’s also three other songs that are gonna be coming out as well.”

“The Dirt (Est. 1981)” features a guest verse from rapper Machine Gun Kelly, who plays drummer Tommy Lee in the film. MGK said he obtained the role after a two and a half year,

“six-audition process. The first two, I was auditioning for Nikki Sixx, and then the last four for Tommy Lee.”

‘The Dirt’ is set to hit Netflix on March 22. Aside from Machine Gun Kelly as Lee, the film stars Daniel Webber as Vince Neil, Douglas Booth as Nikki Sixx and Iwan Rheon as Mick Mars. The film was directed by Jeff Tremaine (Jackass Presents: Bad Grandpa)

Sixx mentioned during the radio program: 

“Anybody can make a shitty rock movie. We don’t want to do that. A lot of people don’t understand rock music and the rock ‘n’ roll lifestyle. It’s not just sex, drugs and car crashes. Those things happen … and, in our case, more than usual. But what’s at the core of it all is the creativity and the personal relationships between each bandmember. We don’t just want to slap together the thrill moments. Any of the great movies, whether it’s ‘Walk The Line’ or ‘Ray’, they got the music right and the personalities right.”
