Created largely by scientists, techies and experimental musicians, lowercase recordings are frequently based on the magnification of minute sounds through a computer, typically a Macintosh.

Apparently you take samples and run them through ProTools, amplify and loop them -- that kind of thing. Not sure where this gets confused as music. These are like atmospheric soundtracks -- soundscapes. More performance art than music to me, but very interesting. They say they're reminiscent of John Cage. I can hear that. Playing one of these in the background of a quiet setting could be very affecting.
