"which laid the foundations of the sound of the 90s". Kevin Moore (keyboardist for Dream Theater at the time) was featured as a guest on the song "At Fate's Hands", while the cover was designed by Hugh Syme, famous for his work with the Canadian progressive rock band Rush. Although Perfect Symmetry was not as successful as No Exit, the album nonetheless charted for nine weeks on the Billboard 200, while its only music video "Through Different Eyes" managed to get some airplay on Headbangers Ball. The album also saw the band embark on their first full-length world tour, which lasted for a year between November 1989 and November 1990; they opened for Manowar in Europe and toured there again with Sanctuary, who had also opened for Fates Warning in the US in early 1990. 1991 saw the release of Parallels, distributed by Warner.

Later years (1994–2009) Slowing down after the commercial success of previous releases, the follow-up to Parallels took two and a half years for Fates Warning to make. The resulting album, Inside Out (1994), continued in the general vein of the previous album while adding more melody to their songs. The band's lineup also remained intact between albums for the first time since Spectre Within. Band members have attributed the album's comparative lack of success to
