Writer/director Shane Carruth’s long-awaited follow-up to the smart (and more than slightly perplexing) 2004 film Primer is poised to be released on April 5th, and now the entire score for the pic, titled Upstream Color, has been made available online for your listening pleasure.  The official logline describes the film thusly: “A man and woman are drawn together, entangled in the life cycle of an ageless organism.”  I caught the pic at Sundance and thought it was great, but if you're hoping for a more accessible film than Primer, prepare to be let down.  I’m still trying to formulate my own idea of what Upstream Color means/what happened in the film, but it’s nothing if not ambitiously original and it's constantly engaging.  You can read Matt’s review right here.

Carruth composed the film’s score himself, and it’s a great piece of music that works wonderfully within the context of the movie.  Hit the jump to take a listen.  Upstream Color opens in limited release on April 5th followed by a gradual expansion before hitting DVD and Blu-ray on May 7th.
