This record was cut using a specialist technique known as half-speed mastering. This artisan process results in cuts that have superior high frequency response (treble) and very solid and stable stereo images. In short, a very high quality master that helps to create a very high quality record. The original cut for this record was half speed mastered at Abbey Road Studios.
Ghost in the Machine, released in October 1981, is the fourth studio album by The Police and the first to feature a title in English, which was of course provided by Arthur Koestler's The Ghost in the Machine, the book that inspired much of the material. The songs were recorded between January and September in 1981, in sessions that took place at Air Studios, in Montserrat, and Le Studio, in Quebec, and were co-produced by Hugh Padgham.
The album reached No. 1 in the UK Albums Chart and No. 2 in the US Billboard 200, spawning three successful singles: "Every Little Thing She Does Is Magic," "Invisible Sun," and "Spirits in the Material World." In the US, however, the song "Secret Journey" was released as an alternative single to "Invisible Sun." No. 1 in six countries and top 6 in five others, sonically (in hindsight) it formed a bridge between their more direct early work and their more ambitious latter direction. In 2000 Q magazine placed Ghost in the Machine at No. 76 in its list of the 100 Greatest British Albums Ever. More recently Pitchfork ranked it No. 86 in their list of the 100 Greatest Albums of the 1980s.
