'Unfolding Skies' is the fourth collaboration between Craig Padilla (keyboard, synths, electronic, programming) and Marvin Allen (guitars) with a much more intense electronic post-rock sound than their previous efforts. Could this even be categorized as "ambient"? Well, sort of, but not fully. Most might agree that Ambient music is a genre of music that emphasizes tone and atmosphere over traditional musical structure or rhythm. That's the big question on 'Unfolding Skies.' There is a good deal of somewhat traditional musical structure and rhythm on it that has absolutely nothing to do with the Eno-esque wallpaper sound, minimal, repetitive structures that form the basis of ambient music. This is much more like conceptual progressive semi-electronic albums put out by Mike Oldfield, Enigma, and Steve Wilson. In fact, if you married latter-day Tangerine Dream with Pink Floyd (or at least borrowed Dave Gilmour) you might get something close to this. (Marvin Allen has the guitar chops Edgar Froese always dreamed of having.)

Comparisons to prog-rock are inevitable but it's more the Floydian style of bluesy, flowing cosmic grooves rather than the Yes/Genesis/Gentle Giant/King Crimson adventurous time changes that often show up in their songs. Although there are 7 individual pieces on 'Unfolding Skies,' in no way could they be categorized as "songs". There are no lyrics, no verse/chorus/verse structures, and sometimes, no discernible melodic theme. Does that make it ambient, or do we just call it cosmic space music? In a sense, it really doesn't matter. What really matters is how it sounds. Yeah, 'Unfolding Skies' is an album you can kick back with, light up a joint, turn on the color organ (or whatever ambient lighting you prefer) and space out to. A good deal of the music was improvised, especially on Mr. Allen's part, but that's what makes it interesting, eschewing static constructs and floating up into the stratosphere. In point of fact, that's what will probably draw listeners back again and again to the album. It is not structureless though, as numerous parts are definitely, but subtly structured. If there is one complaint to be leveled about 'Unfolding Skies,' it is a lack of memorable musical themes. One or two might have been nice. (Even Tangerine Dream's most rock-like album, 'Force Majeure' had some.) This is an album that is meant to be experienced as a whole, not selected tracks. People will be talking about this one for a long, long time.
