New York City disco-punk vets LCD Soundsystem capped their decade-long career last April with a run of hometown shows that concluded with a final night at Madison Square Garden. I wasn't there, sadly, but word is the show was, like, unforgettably amazing, amazing, amazing. It was filmed for a new documentary called Shut Up and Play the Hits, which also chronicles the band's breakup and explores why, exactly, frontman James Murphy wanted to call it quits. In a new teaser clip for the doc, which drops later this year but will screen next week at SXSW, Murphy says his age played a large role in the group's dissolution.

Murphy, 42, says, “I was 38 and said, ‘I wanna make a record.’ I blink and I was 41. I want to have kids and have a life. I blink twice more and I’m 50.”

Watch the clip above, which features a badass rendition of “North American Scum.”
