You’d be forgiven if you didn’t know the music band Bros. In the late 1980s, Bros were the hottest act in British pop. The twin brothers played to sold-out concerts, top ten chart hits and the undying devotion of screaming, swooning fans, dubbed “Brosettes.” Though they enjoyed Beatle-like mania, Matt and Luke Goss called it quits in 1992, refusing to speak for 27 years.

But as any good rock doc knows, no reunion is out of the question — and the documentary After the Screaming Stops offers an all-access pass during the countdown to the Bros reunion concert of 2017. Make no mistake: This is no Behind the Music TV rockumentary. After the Screaming Stops can’t help but focus on the toxic relationship between brothers who sometimes make Cain And Abel seem like best pals. Original fans of the duo will be riveted, but even casual music fans will recognize this is more a story about sibling rivalry.

The title is taken from a question posed to the brothers by the late British television presenter Terry Wogan: What would become of the duo “after the screaming stops?” They found out sooner than either expected. In the weeks after one of Bros’ biggest hits, drummer Luke Goss moved to Los Angeles to pursue an acting career, making appearances in Blade 2, Hellboy 2 and others. Singer and musician Matt Goss pursued a solo career, undertaking lengthy residencies at Las Vegas hot spots including Caesars Palace.

The decision to reunite for an epic concert at the O2 arena in Britain seems motivated by both professional pride and personal demons. The ticking clock to the big day gives the film structure and tension as archive footage of past concerts is paired with confessional interviews. The brothers are generally interviewed individually, and in that solitude both reveal all manner of insecurities, musical and familial.

Like the group Wham!, Bros resent that the British press never took them seriously. Despite being the front man, Matt appears to be the most volatile and vulnerable, lamenting the distance between him and his brother. He also gives Bros its occasional This is Spinal Tap-esque humor. “You need to be on the same page, otherwise you don’t get to turn the page, “ he declares.

There is also a Spinal Tap element to the tempers and tantrums. Rehearsals are as mesmerizing as slow-motion car crashes as the brothers clash. Bros’ success at times seems nothing short of miraculous, given the brothers often can’t seem to bear being in the same room together.

The tension ratchets up as drummer Luke grows frustrated that his viewpoint takes a backseat to his brothers (sometimes tearful) antics. The docu doesn’t shy away from the warts-and-all candor of their arguments. We revisit the death of their parents and the odd reality of being a world celebrity in your 20s.

Like Spinal Tap, if After the Screaming Stops deserves any feedback, it’s for a lack of context. There are no interviews about why the brothers became so big or what make their songs so popular. The film opts not to interview any musical media or academia for insight.

But the comparison with Spinal Tap stops about there. Far from being a mockumentary, the film is a serious look at fame’s effect both on youth and music, and whether it’s doing either any favors. When it gets off stage, away from the lights and stage bravado, After the Screaming Stops cranks up to 11.
