The Rock-In-Opposition movement had a very short shelf life, but produced some of the most amazing avant-progressive rock bands.  Think of acts like Univers Zero, Henry Cow, Art Zoyd, the Art Bears, Stormy Six and others.  Their influence was felt far and wide, and you can hear it in the work of former ZGA guitarist Vadim Petrenko.  He has synthesized the influences of his favorite artists and added his own take on the genre.  His work with ZGA was stunning, so I’m looking forward to hear how he develops as a solo artist.
