There are many 80s rock bands that influenced traditional progressive bands, and Queensryche should be considered among the tops in that genre.  Queensryche set out to establish their own unique sound, and in doing so, set the trends for progressive metal as we know it today. 

Their sound is very melodic and the layered guitars set the stage for a wall of sound in appropriate points in many of their signature songs.  They are masters of dynamics, transitioning from quiet and textured notes to a full blown wail at just the right time.  You can hear their influence on just about any prog band today, which at least in many music lovers ears, makes Queensryche a classic band that will be relevant for many generations to come.
