A follow-up to Drumm's "Imperial Distortion" and an extended journey into ambient sound making, oscillating in the clouds for all he's worth. No raging noise a la "Sheer Hellish Miasma", no particulate, sparse improv as in his earlier work, just an ongoing, medium-volume, booming hum and drone, shades of Aphex Twin.

Is it enough? Not for this listener, though it's very well crafted, internally consistent and reasonably (within its own parameters) varied. Small new elements are added over its 64 minutes � a slight bass throb here, a higher, hornlike tone there. The oscillations waver pleasantly enough; you imagine that were this a live experience, moving through the performance space might produce attractive alterations in implied beats between waves. But overall, it's steady state, far more likely to appeal to fans of ambient music than either noise or free improv. The general sonic tone reminds me a lot of the later stages of Lucier's "I Am Sitting in a Room" though, necessarily, lacking that works' underlying structure and reason for being. Here, one simply floats in the clouds. Those clouds may be slightly tinged with mercuric poisoning � there's enough of an acidic edge in play � but the journey doesn't quite have what it requires to be totally immersive and revelatory on each new listen. Ambient fans may well disagree.
