Rush (1976) Lessons

Starting with a frenetic jangly acoustic rhythm before devolving into giant distorted power chords,  from the slick to the crunch yet not sounding like many other Rush songs it's even got those Zeppelin dynamics not surprising considering their first album was a direct rip off of Zep's style, it was when they developed a sound of their own a heavy prog style. With the tight rhythm section and Geddy Lee's shrill vocals they proved they had their own personality and identity of their own before their early 80s success.
