Some reviews of Sky:
...Spacious, floating, and ethereal, the combined human voices seem to stretch out and envelop everything, blanketing it in a layer of billowy softness. The wonder and awe of "Kyrie Eleison," the "I swear this is a synthesizer" effects on "Passion" and the blissful ambient-like "Uplifting" are songs that should send fans of electronic ambient music into a state of rapture....That it's human voices making these celestial sounds never fails to astonish me.
~ Bill Binkelman, Wind & Wire
...I'm still amazed that these sounds are simply untreated voices... of course, they're overtone singing within a large space, and the results are simultaneously thrilling and soothing.
Lush, diffuse choral strands rise and fall with Kyrie Eleison's continually surging vocal drifts. Ever-expanding layers seem to trace a distant, gently meandering shoreline in human-powered tones that no synthesizer could hope to mimic.
~David Opdyke, Ambientrance
... a sound extreme in both beauty and emotional character....Sky will have the listener returning many times, attempting to both re-enter the zone this music puts one in and quantify an immeasurable factor that borders on the mystical.
~ Chuck van Zyl, STAR'S END
