On September 14 2015, two black holes — 36 and 29 times the mass of our sun — finished a spiral that had been going on for years… In the final 0.2 seconds before they merged, they released more energy than all the stars in the observable universe combined. LIGO detected the resulting gravitational wave that same morning.
That signal is the bed track of this recording.
I took the raw H1 Hanford detector audio from gwosc.org (CC BY 4.0), stretched it 60x using the Paulstretch algorithm, and pitched it down two octaves. What sounds like wind beneath the piano is the actual gravitational wave data processed into human hearing range.
The piano improvisation was recorded live over the top in one take. No edits. No overdubs. No second chances.
🎧 Headphones. The low end is the whole point.
Piano improvisation is entirely live and human. No AI was used in the performance or Improvisation.
