“Kate’s Bored; It’s a Rainy Day.”, by Masaki Kubo & Bruno Ruviaro, is a collaborative composition. A Japanese producer planned to release a compilation CD with electronic tracks made out of skateboarding sounds; we were asked to compose a piece for it. The skateboarding recordings used as point of departure were provided. We worked extensively on those and added a few extra samples of our own. All decisions were made collectively, which by itself is an interesting compositional challenge.
