Ernest Greene of Washed Out says:
I decided to choose a theme off an old OST. Pino Donaggio's "Body Double" (along with the Lovelock edit below) has been a consistent favorite of mine for the past 6 months. I've actually never seen the Brian de Palma film, but this theme makes for an incredible driving song, and I find myself leaving it on repeat quite a lot. The Lovelock edit is called "Pino Grigio", and was released by Mindless Boogie as part of its ongoing edit series. It expands on the original very tastefully, adding a little more dynamic range.
The soundtrack is out of print, but a compilation of Pino Donaggio film scores for Brian de Palma is available via iTunes
