The Black Keys they gave one of their most popular albums the title “Brothers”which appears at first glance to refer to the brotherly relationship between the two members of the rock duo, Dan Auerbach and Patrick Carney.

The question of whether their relationship is sibling can be answered by their fans after watching it “This Is a Film About the Black Keys” music documentary that focuses on some lesser-known, historical tensions between the two, as well as what connects them.

The term “arranged marriage” is heard more than once in the film, which seems a bit odd, given what is known about the duo’s shared biographical details, reports a Variety review.

Jeff Dupre’s film follows the path of Dan Auerbach and Patrick Carney from early musical experiments in a basement in Akron, Ohio to massive success on the rock ‘n’ roll scene.

“They knew very little of each other when they first recorded, but quickly realized they shared a strong musical connection and a drive to succeed. Touring non-stop for ten years, the duo managed the ups and downs of touring life, eventually reaching breakaway speed with the records Brothers and El Camino. With so many forces threatening to tear them apart, the band managed to stay together. 24 years later, they’re closer than ever, still making great music and wondering what’s next.” he says in the synopsis of the documentary that made its world premiere yesterday at the SXSW Festival.

“Their story is really fascinating,” the director told ABC Audio. “‘It’s a story about how these two guys were able to build a friendship on top of this amazing musical bond they have together.’

“As they built this friendship, they often found themselves reluctant to talk to each other about how they felt, and when they did, they communicated to each other through their music rather than words.” emphasized Jeff Dupre, who in the making of the documentary adopted the principle of “let the music tell the story as much as possible”.

“All these songs they wrote over the years, each one captures a moment in time,” he emphasized. “They tell who Pat and Dan were at that moment and what they were going through and what they were thinking and feeling.” he added.
