As great as Brian Eno's non-ambient albums are (the one he did with David Byrne can be downloaded here); I've always been intrigued with this one. It's got more feeling than any other record; just atmospheres, textures and landscapes of the mind- it's also one of the most demanding records I own because of what it asks of the listener.
Most music with words (or even guitars or saxophones or drums or etc.) pretty much tell you how to feel; or rather what the musician was feeling at the time of recording. Eno has stated that his intention with Music For Airports was to defuse the tenseness and anxiety of air travel by creating "sound installations" to be played on continuous loops in the terminal, and as to not be noticeable to the listener. A sort of non-invasive procedure, done musically.
Robert Wyatt helps out on the piano on two tracks; I hate to use the word "track" here because the four pieces are so seamless, it really should be taken as a whole. This is from the 1983 Working Backwards box set so the last track is four minutes longer than the CD or vinyl pressings.
