Ground Resonance is named after a helicopter phenomenon I've been obsessed with for years: when a rotor's vibrations fall into sync with the airframe on the ground, the oscillation feeds on itself — building, amplifying, until the machine shakes beyond all control. Pilots fear it. I think it's the most honest description of a dancefloor I've ever found. I've been DJing for twenty years, and the moments I chase are exactly that: a room and a rhythm locking into the same frequency, energy compounding with every bar, until the only options are lift off or come apart. As a lifelong aviation nerd, software tinkerer, and melodic techno devotee, I finally found the name that says it all — the beautiful physics of losing control.
