Rock in Opposition or RIO was a movement representing a collective of progressive bands in the late 1970s united in their opposition to the music industry that refused to recognise their music. It was initiated by English avant-rock group Henry Cow in March 1978 when they invited four mainland European groups to come to London and perform in a festival called "Rock in Opposition".
Practically ignored in their own country, Henry Cow spent most of their last five years touring mainland Europe. There they encountered many innovative groups who were virtually unknown outside their own countries. What Henry Cow had in common with these groups was that record companies were not interested in their music. (Henry Cow's contract with Virgin Records was cancelled when Virgin found that they were not making money for them.)
Henry Cow decided to expose a few of these European groups to British audiences and organised, with the help of a £1000 grant from the British Arts Council, a festival in London they called "Rock in Opposition" with the slogan: "The music the record companies don't want you to hear". The event took place on 12 March 1978 at the New London Theatre with the following groups performing:
While "Rock in Opposition" was never intended to be a formal organisation, the festival did generate "a lot of press around the world". This prompted the five bands to discuss future plans and in December 1978 they met at Sunrise Studio in Kirchberg, Switzerland to reconstitute Rock in Opposition as a collective. By this time Henry Cow no longer existed as a group, but as RIO's prime mover its former members still actively participated.
RIO's primary aim was to represent and promote its members. It was decided that membership should remain closed and small, although new members would be welcome provided they (i) adhered to "musical excellence" (as evaluated by the collective); (ii) worked actively "outside the music business"; and (iii) had a "social commitment to Rock". Using these criteria, three new members were elected:
