The shimmering phrase that opens Pulse Emitter’s “Bioluminescence” sounds like a movie theater’s cue that the lights are going down and it’s time get quiet. The layers of synthesizer that emerge after the initial chime compel the listener to slow down and observe as if something is beginning to grow. Compounded by the imagery of the track’s title, “Bioluminescence” sounds like the score of a nature documentary that borders on science fiction. The song itself is a series of morphing cycles, of swelling synth growls and melodies that wax and wane — a translation of biological expectation. The shimmering patterns recur in variation and become the remarkable moments breaking up expectation, akin to glimmers of light emitting from a creature.
“Bioluminescence” is one of two Pulse Emitter (Daryl Groetsch) tracks contributed to the four-way 2xLP split on Immune Recording. Each of the four artists — Pulse Emitter, Date Palms, Expo 70, and Faceplant (Aaron Coyes of Peaking Lights) — cover a side of vinyl.
