The IXORA TWIN EDITION is a double disc set. Disc One is an extended version of Ixora, containing an additional bonus track.
Disc Two is an alternate version of Ixora, entitled Twin. Like a remix album it can be listened to on its own, but it can also be played in sync with disc one. So if you can scrounge up 2 CD players, press PLAY on both at the same time, you'll hear a quadraphonic version of Ixora.
