»Betrayal« was originally released on CD by Staalplaat in 1993.

»Betrayal« isn't that far removed from »Veiled Sisters« – while not as minimalist, if not repetitive, as that particular release, »Betrayal« relies on the same basic tools of gentle, steady electronic percussion and low-level bass and keyboard shadings. The most immediate changes lie with the various vocal samples on some of the tracks; while not immediately intelligible per se, you get scraps and hints from them, expressing a range of negative emotions regarding the initial peace pact. At the same time, often a subtle but nonetheless effective sense of omen and dire warning lurks throughout the music; the use of bass tones in particular doesn't seem that far removed from what Massive Attack eventually came up with years later on Mezzanine. Also, as with Veiled Sisters, even the most low-key of changes has a large effect in context, such as the metallic clattering added to the electronic pulsing on the second »Nabius.« Overall, the feeling is meditative; this is the kind of music you could put on for a quiet moment, but it's not exactly easy listening in any sense of the word.
