PJ Harvey contributes two new songs to Mark Cousins documentary

PJ Harvey will premiere two new songs on the soundtrack for a forthcoming documentary. What Is This Film Called Love? will incorporate Harvey's first original material since 2011's Let England Shake.

Described as a "poetic documentary about the nature of happiness", What Is This Film Called Love? is the debut feature by critic Mark Cousins. Shooting took place in the UK, US, Mexico, Canada and Germany, without any script, crew or schedule, according to a press release. "It is made more like a piece of music … It's about a guy, film-maker Mark Cousins, in a city alone, getting drunk, walking, dreaming."

Harvey's two new songs, Horses and Bobby Don't Steal, will appear alongside work by composers Simon Fisher Turner and Espen J Jorgensen. "Her music gives the film storm clouds, power," Cousins wrote on Twitter.

Although an official release date has not been announced, an unfinished version of What Is This Film Called Love? will be shown at this month's ATP I'll Be Your Mirror festival in London. Louis Theroux will curate the screenings on 27 May and will presumably moderate the accompanying Q&A with Cousins.

Let England Shake, Harvey's eighth studio album, won the 2011 Mercury prize.
