Lineup
This year’s musical journey weaves together the organic and the electronic — from groovy b2b’s and hybrid sets to melodic, progressive sounds and organic with live instruments. With Budakid (Anjunadeep, Last Night On Earth) and Peter Makto (Soundgarden, Hoomidas) headlining the festival, expect emotional sets that will bring us together. Let’s dance, connect, and feel it all.
