To speak to Luca Daniel Schwarz aka LDS about his music is to be enthusiastically guided into a complex world of his own creation: clean and powerful techno which pulses with life from the textured patterns and drum sequences that have fills and accents that would make anyone who's picked up a set of drumsticks envious.

Yet this ecosystem of noise is deceptive; Schwarz's process for making music is very different to how a live drummer would create the same subtlety of performance. Forever researching new technology, Luca got deeply interested in different programming languages, and created a series of probability based music tools for manoeuvring sounds and sequencing.

Manipulating those probabilities takes a skillful alchemy, needing understanding of both musical structure and how the tools he devised work. To return to the drummer analogy, if the drummer is focussed and intentional in the moment of playing, then the method used in LDS tracks is almost diametrically opposed, with all of the intention coming in the assembly of the instruments, potential paths, and gateways; once play is pressed the music flows, following all the rules that were set in advance, not unlike a domino run or Rube Goldberg machine.

And like a domino run, the results are fascinating and, ultimately, fun: staccato vocals pop in and out in 'zipp prompt'; laser-like synths pulse; background noises sweep across the aural plane of the dub techno of 'diff, blockmix' and 'pow' adding texture that brings vitality all-too-easily missed out when complex mathematical processes become entwined with music creation. The high sensitivity to texture and rhythmic detail in Stadion Progg is multiplied further on Jean Redondo's remix - whose track, Hypersonic, was the backbone of 2023's 'yet' compilation on Tresor.

The balance between technology and a sense of fun might also come from the maker; it's not easy to overstate Schwarz's passion for what is now his favourite way to make music, "it never gets boring. There's always a moment of anticipation to see what actually emerges." And the true "power of 2" comes into play when the resulting music can be fed back through the system again and again, potentiating the music in exponential ways.

Introducing to you "U-Topic Guests": a series of mixes from national and international artists, who's art we admired and want to share it to the world.

The 28th guest is special one, as they were born in Paraguay, but have lived in Switzerland since they were 2 years old.

Zadkiel (they/he) is a Swiss-Paraguayan DJ who seeks to rethink rhythms through broken beats, delayed kicks, electrifying tension, and a relentless groove that pulses with raw, old-school energy. Dance with it, dance against it but let it break you.

An active member of the Neuchâtel-based collective Retroblast, they’ve been deeply involved in the local scene for several years, not only as a DJ but also as a visual artist. 

Under the alias of HZJM, they've been working with graphic design, photography, and video to create a multidimensional world shaped by shared themes: dreamlike aesthetics, alterity, club culture, queer identity, and the fluid dialogue between mediums.

Since 2023, Zadkiel has performed in key venues across the Swiss scene, including SAS (Delémont), La Case à Chocs(Neuchâtel), La Coupole (Biel), and Festi’Neuch, sharing line-ups with artists such as The Lady Machine, MCR-T, Miss Bashful x DBBD, and Shoki287. 

Their musical inspirations span a wide range but when it comes to techno and electro, it includes Gary Beck, Helena Hauff, JakoJako, Luke Slater, Nur Jaber, Polygonia, Surgeon, Yanamaste, and more.
