Nearly four decades after the release of their debut album, The Go-Go’s still have the beat. A new doc chronicles the iconic girl group’s meteoric rise and sees them reteam for their first new recording since 2001.

“We are the first all-girl band that wrote their own material and played their own instruments to be really successful. In the course of a year we had gone from playing dive bars to Madison Square Garden,” a member explains in a new trailer for the doc.

The Go-Go’s first album, 1981’s “Beauty and the Beat,” was No. 1 on the Billboard charts for six consecutive weeks and scored them a Grammy nod. The album included mega hits “We Got the Beat” and “Our Lips are Sealed.”

The group emphasizes that “there never would have been The Go-Go’s without the punk rock scene in Los Angeles,” which we’re told “allowed you to be whoever you wanted to be, play however you wanted to play, and you were accepted.”

The spot also touches on the toll that fame and success took on the band, including a communication breakdown among its members.

The Go-Go’s is comprised of Charlotte Caffey (lead guitar, keyboards, and vocals), Belinda Carlisle (lead vocals), Gina Schock (drums), Kathy Valentine (bass and vocals), and Jane Wiedlin (guitar and vocals).

Check out the trailer to hear what the band describes as “probably the best feeling in the world.”

Directed by Alison Ellwood, “The Go-Go’s” premieres on Showtime August 1.
