Hemispheres is Rush's 6th album. This album continues Rush's trend of using the fantasy and science fiction lyrics written by Neil Peart. Though science fiction is not present so much on this album it does contain fantasy elements. "Hemispheres" and "The Trees" are good examples of this.
Good examples of Rush's conformance to progressive rock standards include the use of fantasy lyrics, complex rhythms and time signatures, and flexible guitar solos, like those in "La Villa Strangiato".
