In times of shrinking sales of audio formats, more and more artists are seeking refuge in the field of commissioned composition, whether it be for commercials, dance, theatre or, in this case, film. And as if Rostam Batmanglij, producer and multi-instrumentalist of Vampire Weekend, doesn’t have enough to get on with, maintaining two parallel adventures, Discovery(the electro-pop meets R&B project he shares with Ra Ra Riot’s Wes Miles) and Boys Like Us (his solo project, for now more active as remixer than anything else), the man still has time to write the odd soundtrack. Batmanglij was in charge of composing the score of “Sound of My Voice”, a film –you can read its synopsis here– to debut at the end of January at the Sundance Film Festival. If you look at the film’s credits, you’ll see it’s a work by Zal Batmanglij, Rostam’s brother, keeping it close to home. By the way, did you know that Vampire Weekend have just released their “iTunes Session”? You know where to look for it.
