The first strains of the opening track, serve as a bridge from the earlier Drifting in Silence work; but any expectations that UnknownDivide will be more of the same are quickly blown away. The ephemerality of "Ephemeral" immediately steps aside to present a taste of the powerful and complex rhythms in store. Spritely timbral highs rescue the deep percussion from becoming ponderous. Together, they keep everything moving. But, lest the listener object that this two-minute intro is over too soon, have no fear; "Ephemeral" is merely the hors d'oeuvre.
