It's difficult to summarize Rush into any one rock genre. The band's sound has evolved a great deal over the years, but they've always been a trio that delivers complex, intricate music. Some of their most notable musical periods include:

- Early Zeppelin-like days of the mid '70s

- Out-of-this-world prog masterpieces of the late '70s

- The classical-inspired period of the early '80s

- The heavy-synth days of the late '80s

- The return of muscle, metal, and brawn in the '90s and on
