Overview:Hemispheres, Rush’s sixth studio album, was originally released in October 1978, and it built upon the adventurous sonic template the band established on its acclaimed 1977 effort, A Farewell To Kings. The album’s first track, “Cygnus X-1 Book II: Hemispheres,” encompassed the entirety of Side 1 on the original release and was the logical, heady continuation of the epic album-ending Kings track, “Cygnus X-1.” Side 2 commenced with the hard-driving commentary on English culture “Circumstances,” followed by the socially aware and environmentally conscious FM radio hit “The Trees,” and concluded with the instrumental tour de force and longtime concert favorite, “La Villa Strangiato.”
