This album by John Carpenter titled "Lost Themes". Released in 2015 by Sacred Bones, this CD contains 49 minutes and 13 seconds of music. These are themes that Carpenter developed and performed with his son and Godson during his retirement phase. They are not themes belonging to any of his actual films but all kind of sound like they could have been lifted from any of them. Hints of Halloween, Escape from New York, The Thing, Prince of Darkness etc can heard throughout.
