Pretty much. Not surprisingly, Wikipedia does a much better job explaining it than I did [1].
Zaireeka is the eighth studio album by American rock band The Flaming Lips,
released on October 28, 1997 by Warner Bros. Records. The album consists of
four CDs designed so that when played simultaneously on four separate audio
systems, they would produce a harmonic or juxtaposed sound; the discs could
also be played in different combinations, omitting one, two or three discs.
Each of its eight songs consists of four stereo tracks, one from each CD.
