Progressive Rock all but disappeared from the public airwaves from the mid 1980’s to the 2000’s due in most part to label consolidation which carried by default, economic and creative constraints, creative control and a subsequent narrow vision of music content.
However, by the mid to late 1990’s, technology once again changed the music playing field as computers, computer programs, the Internet and the home recording studio provided artists with new cost-effective tools to create music and reach an audience without having to knock on closed Industry doors.
Music expression exploded across the Internet reviving the political voice at a level not heard since the early days of Progressive Rock. Mainstream artists joined in and gave the public a stronger voice. Although I will note that Roger Waters has always been vocal and a champion of the down trodden.
Progressive rock had been synonymous with free speech, activism and the anti-war movement in its earlier days (1967 to 1975), so when progressive rock surged in the 2015 to 2019 years, it was due to a growing political enlightenment in the world at large; and it became a global phenomenon.
