How Underground House Music Shaped the Festival

Long before the Mainframe rig existed, underground house was passed hand to hand — white labels, basement rooms, word of mouth. We trace that lineage and show how it shaped the Sonorous booking philosophy: patience, warmth, and selectors who read a floor.

From Chicago basements to our Mirage Dome, the thread is unbroken. This year's programme dedicates its opening night to that sound.
