With 2012-13′s One Last Tour, the trio of Axwell, Sebastian Ingrosso and Steve Angello elevated to an arena-level status rarely experienced by any band, let alone a trio of Swedish DJs spinning euphoric dance music.

Engaging new film documentary Leave the World Behind beautifully captures the dazzling spectacle that followed the group as they circled the globe on One Last Tour, hitting 26 countries and playing to more than one million fans on the unexpected farewell jaunt marking the decision to break up when Swedish House Mafia was at the peak of its powers and arguably the biggest band in the world.

There's a scene early in the film that finds Axwell sitting on a private plane between shows, contemplating the legacy Swedish House Mafia will leave behind. He imagines a scenario where the group would someday be the subject of a one-hit wonder show, forever remembered as the band that broke up too early, going on to fading degrees of solo success until one of them ends up a crack addict. All tidily summed up with a spin of the band's biggest hit, 2012′s "Don't You Worry Child," which hit No. 6 on the Billboard Hot 100. He laughs, but wonders aloud if the band is throwing away "the key to the golden city."

Leave the World Behind presents a compelling tale of how the three DJs first came together and in a few short years grew into a global phenomenon over the course of essentially just six singles. What soon becomes apparent is that no one, least of all the DJs themselves, ever really imagined that their brand of purposefully uplifting dance music would play such a pivotal part in breaking the sound in America and help open the floodgates for EDM to become a driving force in U.S. youth culture.

Given the group's rocket trajectory, the movie also shows how success and the usual trappings that come with it affected each member, magnifying cracks in their personal and professional relationships into huge chasms that led to the abrupt break-up. An uneasy tension runs through the film as SHM is seen flying around the world, creating magical moments for massive crowds of ecstatic fans from its home base in Stockholm, Sweden to India, Austria, Malaysia and beyond while the band slowly unraveled.

It's a stark juxtaposition, with the members openly questioning why it was their last tour, and each one coming to grips with it in their own way. Ultimately, breaking up was the only way they could see to preserve the legacy of the band at its best before it could descend into shattered friendships and the tragic, cliche scenarios of so many "Behind the Music" stories.
