After announcing that their upcoming documentary “Leave The World Behind” will debut this March at SXSW and releasing the official trailer, Swedish House Mafia has released the first teaser clip from the film. Because it wouldn’t be modern-day music documentary without tearful fans, the brief clip shows Axwell and Steve Angello autographing a t-shirt for a girl who’s so happy she’s sobbing. Before she goes, Axwell tries to make her laugh. Twist: she cries more. The site for Leave The World Behind indicates there will be 11 more clips released before the film premieres on March 12th in Austin, exactly two years after the trio unleashed “Greyhound” as a single. Stay tuned.
