For France-born, Berlin-based conceptual composer David Letellier (artistic alias: Kangding Ray), the combination of slowly swelling melodies and emotionally charged machine sounds gives way to a sensitive, rhythmic symphony of staggering beauty. This juxtaposition of organic and synthetic, of acoustic instrumentation and digitized beats, reflects Letellier's wide-ranging creative background. The interdisciplinary artist studied architecture and played guitar and drums in a number of rock, pop and jazz formations before embarking on a more kinetically-charged electronic mission. His darkly textured techno grooves – a palette of throbbing bass lines, necromantic synths, processed guitar loops, rattling walls of distortion and unorthodox field recordings – accounts for a brooding, future-retro entity that elicits both lab-coat admiration and club culture emancipation. His glitch-y, experimental pop anomalies have been released on authoritative imprints such as Raster-Noton and Stroboscopic Artefacts. After having performed at Elektra, Ray returns to EM15 to present a hardware-strong, industrial techno live rendition of his dense, holistic fourth album, Solens Arc (2014).
