Edge of the Universe is a prequel in William Edge's musical Sci-Fi trilogy about a journey to the edge of the known universe. It was actually the second album to be released, hence some of the musical refrains are familiar. Musically it has more in common with the last disc in the series -- Beyond the Edge: Into Infinity -- than with the first one which is funkier and livelier. Fourteen standalone tracks ranging from a little over one minute to nearly nine minutes comprise the album. Of these the first up is "Reflected Light" on which a variety of squiggly refrains flit here and there over the top of cosmic synth pads. Things settle down in the second track "Spectrum", a melodic piece with gentle rhythm and melody plus occasional electric piano that is redolent of passages on Beyond the Edge. Adding to the musical narrative is the voice of Cheryl Lipner again, this time on the track "Discovery" recounting events leading up to the mission to the edge of the universe. She speaks over a mid-tempo puttering of electric piano refrains and gentle bass while electronic effects glide past like ephemeral star trails. Who knows what would be discovered at the far reaches of space? Maybe it'd be something like "Energy Form 1". The sounds on this track have a kind of set back feel as drum beats veer around, as do eerie synth washes that sometimes have a vaguely voiced edge to them. More obvious voice effects can be heard later in the piece "Revelation". Closing the album is "Epilogue", this very short piece initially has space mission dialogue which can just be discerned through Morse code and intergalactic static. The recurring musical theme then comes in, and as a bridge to the second album in the trilogy the narrator tells us about the mission. Big ideas and spiritual reflection are the mainstay of this musical trilogy. On the whole it works well, even though it doesn't move far from some core musical themes. Edge of the Universe is another solid release in this series, its quasi melancholy takes you off to the farthest reaches of space for over an hour of an intense but satisfying experience.
