The premise for “Roadies,” a music drama that chronicles the lives of a popular rock band’s road crew, originated back in 2008, executive producer J.J. Abrams told Variety Monday night at the Showtime series’ Los Angeles premiere.

Though Abrams and “Roadies” creator Cameron Crowe discussed the project for a number of years, neither was sure if the series would ever come to fruition. That was until Crowe paid a visit to Abrams’ Bad Robot Productions a few years ago and began penning the script.

“He wrote a script that was, for years, this thing I’d been hoping I would get to read, which is Cameron Crowe’s experience with the people who are in the shadows running these shows that never get any of the spotlight or recognition– it’s the passion of music that brings them together,” said Abrams, clarifying that “only Cameron could have done this.”

Crowe also commented on the writer-producer duo’s longtime relationship, adding “We made a promise to each other that if I were to ever enjoy the benefits of working in TV, we’d do it together.”

Like Crowe’s 2000 drama “Almost Famous,” which drew inspiration from Crowe’s stint as a music journalist and earned the auteur his first Oscar, “Roadies” boasts a “based in reality” storyline.

“We either saw it, knew it happened, heard it happened or knew it to be true, so that everything would be authentic,” Crowe said of “Roadies'” plot details.

The pair was joined on the red carpet, which was stationed at Downtown Los Angeles’ historic Theatre at Ace Hotel, by co-stars Luke Wilson, Carla Gugino, Imogen Poots, Rafe Spall, Peter Cambor, Richard Colson Baker (aka Machine Gun Kelly) and executive producer Winnie Holzman.

“Roadies” premieres June 26 on Showtime.
