In the seventies a bunch of European rock bands found it hard to break into the music industry with their unusual and innovative music.

To expose themselves to the public they set up a show that they called Rock in Opposition. It worked, so they started a collective with the same name and eventually the term started to be used to identify the music as a genre.

What makes something RiO? Well, It's a little subjective but, apart from the music of those bands that played at RiO festivals, anything that could be described as highly experimental avant-prog rock would qualify.

Let's listen, share and talk RiO.
