Hemispheres is the sixth studio album by the Canadian rock band Rush, released on October 24, 1978, by Anthem Records in Canada and Mercury Records elsewhere. After the commercial and critical success of A Farewell to Kings (1977), the band returned to Rockfield Studios in Wales to record the follow-up with long-time co-producer Terry Brown. The recording process was notoriously difficult, with the band spending several weeks writing and arranging the material in the studio, a departure from their usual practice of entering sessions with completed songs.
