Ghost is the fourteenth studio album by Canadian musician Devin Townsend, and the fourth of five albums in the Devin Townsend Project series. It was released on June 20, 2011. Townsend has stated that the album "is the mellowest (by far) and prettiest record I've done so far".
Ghost was performed in its entirety once, on November 13, 2011, at the Union Chapel in London, England. The performance was filmed and recorded for the By a Thread – Live in London 2011 CD/DVD box set, along with performances of the other 3 Devin Townsend Project albums.
The song "Drench", a leftover slated to appear on a second volume of Ghost, was shared by Townsend on his official SoundCloud account. Later, Mackie Gear posted the leftover track "Fall" on SoundCloud.
Ghost 2 was originally to be released in September 2011. Ghost was originally to be a double album, but ended up being a released as a single disc. Ghost 2 would have included tracks that weren't released on Ghost. Devin Townsend has stated that these tracks were "too dark" and "heavier" then the rest of Ghost, which didn't fit the vibe of Ghost. On August 22, 2012, Townsend officially cancelled Ghost 2, saying, "I tried to finish Ghost 2 the other day, but it's not solid enough. Doesn't engage. Going to use the best bits and art for elements of Z²." Some of these songs were eventually released on the bonus disc included with Casualties of Cool.
