A prior post here covered the amazing first collaboration by Robert Fripp and Brian Eno, 1972's (No Pussyfooting) and, at some point, we'll have to delve into the remarkable Evening Star from 1975, as well. As for Eno's solo work, however, that has only recently been explored and it's really too bad that it's taken so long.
Ambient 1/Music for Airports, released in 1978 on Editions EG, is an astounding recording and one that has an eternal feel to it and, to this listener, does not sound as if it is almost a half-century old. What's notable is that, as Eno did with Fripp on the aforementioned albums and then on his own Discreet Music, also from 1975, he utilized tape looping of notes that either came in small clusters of three or four or of sustained tones with the timing based on the length of tape used. These variations allowed for the establishment of new patterns or development of sounds.
The first piece "1/1" features Soft Machine's Robert Wyatt playing a piano, while "2/1" and "1/2" incorporate the voices of Christa Fast, Christine Gomez and Inge Zeininger singing one sustained note for ten seconds and then these looped, with piano utilized again in the latter piece. Eno once stated, "I just set all of these loops running and let them configure in which ever way they wanted to, and in fact the result is very nice." That it is and the feeling is of immersion in the sound world created.
Not unlike Anthony Braxton, Eno, who, though, does not read music, developed a graphic score for each piece, reproduced on the cover. Each, however, represents the compositional approach of the phrasing and looping undertaken. Employing the strategy recommended by Donald Ayler, whose brother, Albert, was a powerful force in free jazz, especially in the last half of the 1960s, to follow the sound, not the notes, letting this music be an experience.
Eno, in fact, was inspired by sitting in an architecturally compelling airport in Cologne, Germany, but was struck by the piped-in music being incompatible, in his view, with the surroundings. This was his concept for how such a musical environment could be developed and introduced, though he also said in an interview that the idea that a traveler could end up in a fatal plane crash was a major part of this thinking. As relaxing and enveloping as this music is, that is certainly not the impression left for this listener!
