It's been eight years since Sophie Muller and The Kills' collaboration for Last Day of Magic back when bandmates Alison Mosshart and Jamie Hincehave where beating the living daylights out of each other in hotels and back alleys.

Seems like they're getting along just fine now in Sophie's playful fourth video for the duo, Heart Of A Dog, which gives us a glimpse into their shared creative lives, made up of a dynamic patchwork of images. Captured across a day in Los Angeles, it's a really quite lovely piece of work, and seems to get at the heart of their dynamic - one of writing, travelling, taking in the sun, making music, playing around with each other... with a few backflips thrown in.
