Lucrecia Dalt and I shared a bill in Milan and I wanted to celebrate her album, Ou, being sold out. I made a photocake with the “Negative Money” business model printed on it and I decorated it with sparklers. I lit each sparkler at the same rate as her download sales (only faster). I also played the sound of fireworks in a rhythm that corresponded to the rate of vinyl sales (as a sonfication). Then I served the cake to the audience.
