Although it's not on the same level as the best progressive bands – the drums and keyboards are not really up to the challenge presented by the guitars – this album has been rather unfairly written off by some music critics. Their debut begins with their strongest composition: "Voices," whose multiple movements, chorus lyrics of "a million voices singing," broad washes of mellotron, and alternating guitar tones make it sound like an outtake from Yes's "The Ancient." The instrumental "Theme" has some fine jazz-prog sax soloing over a lush backing, and "Dawn of Evening" has a wonderfully taut bassline march pushed to the front of the mix.

An epic adventure begins when a massive sinkhole opens in the middle of Los Angeles, pulling hundreds of people and buildings into its depths. Those who fell in find themselves in a mysterious and dangerous primeval land, where they have no choice but to band together to survive. Meanwhile, the rest of the world desperately seeks to understand what happened. In the search for answers, one family torn apart by this disaster will have to unlock the secrets of this inexplicable event to find a way back to each other.
