In the eyes of prog-rock nerds all over the world, Dream Theater is one of the most highly respected and influential metal bands in the history of the genre. Even though they are not the only band to pioneer heavy music within the progressive realm, it is not irrational to say that Dream Theater is perhaps the most beloved; alas, each of the band’s members has enjoyed their fair share of individual popularity. Via solo records, magazine articles, and even instructional home videos, it is no secret that all of Dream Theater’s members are experts. Mike Portnoy’s “Progressive Drum Concepts” home video dozens of times practically taught a generation how to grasp odd-time signatures behind the kit. Everyone has a guitarist friend that’s always mesmerized by master riff beast John Petrucci’s legendary “Rock Discipline” home video.
