Originally released in October 1981, the fourth studio album by The Police was #1 in the UK album chart and a multi-platinum best seller. It features three hit singles: 'Every Little Thing She Does Is Magic', 'Invisible Sun' and 'Spirits in the Material World'. Their jazz influences became more pronounced, but the album had a very strong, sophisticated pop appeal, in the song-writing talents of Sting. Highlights also include the vicious jazz-rocker 'Demolition Man', the frantic 'Rehumanize Yourself', and a pair of album-closing ballads 'Secret Journey' and 'Darkness'.
