interlude track "Pagan" on Signify uses the same operatic sample previously used in the ending of "Colours" from No-Man's Lovesighs – An Entertainment. Reception Reception for the album has been mostly positive. Sputnikmusic gave Signify five out of five stars, applauding the album as "a masterpiece in modern psychedelia", writing that it "exudes a raw feeling of musical passion and pure trippy atmosphere: the soaring, expertly written vocal harmonies, engulfing instrumental pieces, unsettling samples, and puzzling abstract lyrics." AllMusic gave the album four out of five stars, praising the album as "... the next great step forward for Porcupine Tree, a distinct advancement in how well the foursome could completely rock out as well as find its own narcotic style of ambient exploration...For all that Wilson may once again be singing obliquely on the pressures and nature of end-of-century life, he still does so in an engagingly left-of-center way." Track listing Insignificance and second disc In 1997, a collection of b-sides and demos from the Signify sessions, titled Insignificance, was released on cassette tape. When Signify was reissued in 2003 on Delerium Records and in 2004 on Snapper Music, Insignificance was packaged as a second disc of Signify, with a slightly altered track list. The later re-releases do not contain the tracks "Door to the River" or "Insignificance", as they were included with the rest of the full band tracks on Metanoia. Still, the compilation retains ten tracks through the inclusion of the track "Dark Origins" and the indexing of Hallogallo/Signify into two separate tracks (despite still running continuously from one to the other). Other tracks B-sides from the era, including "The Sound of No-One Listening" (from the "Waiting" single and the original vinyl pressing of Signify) and "Fuse the Sky" (a remix of the title track from The Sky Moves Sideways released on an ambient compilation) appear in addition to the aforementioned "Signify II" and "Colourflow in Mind" (an album outtake) on the compilation album Stars Die: The Delerium Years 1991–1997. Additionally, an album of studio improvisations from that period, called Metanoia, was released in 1998. The improvisational sessions contained both previously unreleased material and material that was shaped into previously released songs; a track called "Metanoia I/Intermediate Jesus", an over 14-minute long freeform jam, was edited down to serve as the main backing track for the song "Intermediate Jesus". The tracks "Door to the River" and "Insignificance" are
