“Luminiferous Aether” is the first single and opening track of Ignacio Córdoba and Agata Ciurkot’s album “Ephemeral, Basal”, out January 17th, 2025, via Pink Cotton Candy. This improvisation-based composition – blending jazz, ambient, modern classical and electronic music – is a romantic ballad that intertwines processed piano with repurposed industrial oscillators. In the realm of science, luminiferous aether was once understood as the medium through which light travels – a concept long abandoned. This composition seeks to invoke exactly that sense of light’s apparent wave-based ability to move through empty space, and the record as a whole becomes a metaphorical love letter to the lights and shadows of the unknown. An anonymous word triggers Ciurkot’s piano in a sonic vacuum and Córdoba’s synthesizer joins in with shimmering pulses and bass-heavy heartbeats. Together, the instruments and musicians converge, filling the space with bright, ethereal emotion, as if reaching a spatial plenum—a realm entirely suffused with luminiferous aether. Flares, echoes, sound waves, blinding lights, harmonies, reflections, and distortions weave in and out of darkness, culminating in a climactic coda of nearly doom-like piano chords and resonant 808 kicks. “Ephemeral, Basal” was recorded in Berlin and Copenhagen, the cities where the artists reside.
