This album marked a transition from the rock-based music of Eno’s previous releases toward the minimalist instrumentals of his late 1970s ambient work. Only five of its fourteen tracks feature vocals. Employing tactics derived from his “Oblique Strategies”cards for guidance, Eno utilised a variety of unconventional recording techniques and instrumental approaches, reflected in unusual instrumental credits such as “snake guitar” and “uncertain piano”.  The album has made several top albums lists. Pitchfork placed the album at number ten on its list of greatest albums of the 1970.
