Belgian RIO/avant-progressive rock band formed in 1979 led by guitarist/composer Roger Trigaux. Disbanded in 1985 and reformed in 1993. It came as a side project from Belgian avant-garde group Univers Zero. As guitarist Roger Trigaux left that band, he got help from Marie-Anne Polaris (vocals), Alain Rochette (piano), Christian Genet (bass) and Daniel Denis (drums).
