Conet Project (Aquairus Records)

This is definately some of the strangest stuff you have ever heard. I heard an NPR piece on the album and some of the legal battles that have surfaced around it. Wilco used samples, got sued and lost. Anyway go to the link and listen to the pieces.
[ found sounds, field recordings, oddities ] titles at Aquarius Records: "Basically, the Conet Project is a four-cd compilation of recordings of mysterious shortwave radio broadcasts, known as 'numbers stations'. These numbers stations are generally believed to be encrypted spy transmissions, but no concrete evidence has ever surfaced proving that suppostion. However, no credible *alternate* explanation has ever been demonstrated, either. For years (ever since the start of the Cold War), amateur radio enthusiasts have come across these sinister signals, and they continue to this day, broadcast in many languages all over the world (the theory is that some are CIA, some are KBG, some are Mossad, etc).
In general, the transmissions consist of a deadpan voice (sometimes an old man, sometimes a young woman, etc.) reading a seemingly random, meaningless series of numbers over and over. Sometimes the broadcsts are preceded by a musical cue (the 'Swedish Rhapsody' music box one being a favorite of ours), and sometimes the numbers are not conveyed by voice but by even more cryptic electronics (as with 'The Buzzer', and other noisy, abstract stuff found mainly on disc four)."
