The music that comprises Dhūpa, the new release by Dirk Driesen under the name BpOlar, brings rich texture to dark tones. The effect is appropriate for an album named for the word, in Hindi, for incense. The sounds are ritualistic and dread-inducing, and while the effect is monastic, the feel is entirely modern. Here, by way of example, is the second of its four tracks, “Nag Champa,” which mixes industrial drones, field recordings of uncertain provenance, and distorted verbal communication (MP3).
