Ping-Pong Player Piano

Steven Vinkenoog (Haarlem 1970) is a composer, sound artist and guitarist from the Netherlands. 
He went to an awful lot of art schools, institutes and universities, and has been playing in bands since the early eighties. 
Somewhere in the year 2000 he started making guitar based sound installations, which eventually resulted in making open ended scores with an interest in improvisation and process music, very much aware of the social aspects of playing music together.
You might also know him as one half of the musical slapstick duo Donné et Desirée.
