"Slowly oscillating waveforms for deep listening". So states a note on the cover of this disc, and for once we get truth in advertising. This is drone music for sure, but it really doesn't ever stand "still". Constantly evolving through manipulations of timbre and pitch. Attention is rewarded by its shifting details. It reminds me very much of a James Turrell installation, and I think it would work nicely as a soundtrack for one.
I would place this gingerly in the category of meditation music, without the syrupy sweet consonance that saturates most "new age" muzak. People who come to music to be engaged on an emotional level may find Le Sacre a tad wanting, but anyone who slows down and listens will find a vast unfolding presence. It almost seems like a heroic act, to make music like this in the midst of our current turmoil, so I'd say Jonathan Deasy is to be commended for his efforts.
I found myself wondering how this music was made, but only for a moment, slipping back into open ears and just paying attention. We could all stand to do that more.
