It's a must-have album. Includes the first use in a widely distributed CD of nonoctave tunings. The title track combines Carlos Alpha tuning and Carlos Beta tuning, and is really a beautiful and mystical composition. Carlos talked about her process of discovering Alpha and Beta in a Keyboard article, and also in a Computer Music Journal article.

Karlheinz Stockholm (sp?) did some work in a nonoctave tuning (25th root of 5) many years before, as did Heinz Bolhen (13th root of 3) and Kees van Prooijen. All these works by these composers, while worth hearing, are a bit more academic or experimental sounding.

Carlos' composition doesn't sound academic at all, but like an organic work that came from the ancient traditions of some incomprehensible alien culture. It is something you can listen to a thousand times and not grow weary of.
