Equinox, released by Styx in December 1975, holds a significant place in the band's history. It marked their fifth studio album and their debut under A&M Records, following their earlier success with the single "Lady" in 1973.
The lead single from Equinox, "Lorelei," became a notable achievement for Styx by becoming their second song to break into the US Top 40 charts. This success helped solidify their position in the rock music scene of the 1970s.
Equinox also marked a transition for the band, as it was the last album to feature original guitarist John Curulewski, who departed to focus on family matters. He was replaced by Tommy Shaw, who would go on to become a crucial member of the band and contribute significantly to their future successes.
Despite not reaching the highest chart positions initially (peaking at number 58), Equinox attained Gold certification in 1977, reflecting its enduring popularity and sales.
Critically, the album was noted for tracks like "Light Up," described by Record World as an "uptempo effort" with a "clean sound and infectious hooks." This highlighted Styx's ability to craft catchy, well-produced rock music that resonated with audiences.
Equinox, therefore, stands as a pivotal album in Styx's journey, setting the stage for their subsequent breakthroughs with albums like The Grand Illusion (1977) and solidifying their reputation as one of the prominent rock bands of the era.
