Fire can sound like water. Passing traffic can sound like the rush of waves. And in the hands of Thomas Park, aka Mystfied, what appears to be the sounds captured in a dark cavern are transformed into something radiant. The album, a single track more than 20 minutes in length, is titled The Luminous Deep. Phillip Wilkerson is credited with “some of the sounds,” and the cover art depicts just the sort of place one might come upon fellow Deep Listening spelunkers like Pauline Oliveros or Stuart Dempster. The sounds may be sourced from somewhere other than the pictured location, but the effect would remain the same: less the soundtrack of the place than the internal soundtrack of the experience of the place.
