SWO performances are concerned with breaking the border between spectators and musicians, as well as the common restriction of the traditional formats of music (music has a beginning and an end) and its hierarchy (e.g. a classical orchestra).
SWO picnic invited participants to meet at a given time and place to perform together, everyone in their own manner and to their own liking. Participants were asked to either bring a sine wave generating object or make use of the provided spherical sine wave generator, each battery driven and furnished with a loudspeaker and a light sensor, changing frequency depending on light intensity.
