Koyxeи is one of the many aliases of Kouhei Matsunaga, when in his Hip Hop/Breakbeat guise with vocalists & MCs.  Born in Osaka, Matsunaga is a musician and drawing artist dividing his time between Osaka and Berlin.  He started drawing during his childhood under the influence of his grandfather.  Growing up listening to hardcore-techno and hiphop, he first studied architecture, before beginning to make music in 1992.  His first album “Upside Down” was released by Mille Plateaux (Germany) in 1998.  This led to collaborations with Merzbow, Sensational, Autechre’s Sean Booth, Mika Vainio, Conrad Schnitzler, Anti Pop Consortium’s High Priest and more.

By 2002, Matsunaga had started his own label, Flying Swimming.  Under this moniker, he curates unique events for experimental contemporary music and art.
