c3zium

c3zium is a DJ and producer based in Belgrade, and the founder of Hands On, the music performance lab the show is filmed in.

His home turf is drum & bass: neurofunk and dancefloor-facing mainstream DnB, with liquid and deep rollers either side of it. He opened Sonic Shift with episode #01 and has since recorded more episodes for the show than any other artist.

He produces as well as plays. His remix of Танюша's "Антидепрессанты" came out on the КОСТЁР label and has been played at Pirate Station, Neuropunk 360 and Koster label festivals; he dropped it into his own #03 set for the show. Spotify also lists his remixes of "Колоритная" (2023) and "Аватары" (2024), and a 2026 single, "Belgrade & Bass". His #14 set opened with his own drum & bass rework of Tchaikovsky's "Dance of the Little Swans", and his #10 set carries two of his own edits: a Boomergy mashup mid-set and the Антидепрессанты remix as the closer.

For the show's relaunch in July 2026 he stepped outside his own genre and played episode #32 as an all-vinyl house set.
