Signify is the fourth studio album by British progressive rock band Porcupine Tree. It was released in September 1996 and later re-released in 2003 with a second disc of demos, which had previously been released on the b-side cassette tape Insignificance, and a third time, on vinyl, on 9 May 2011.

Barbieri's goals for his contributions during the Signify sessions were "...to use what in isolation would be a weird and abstract sound or texture and to make it work in the context of a pop song". Wilson said of the recording process: "Signify was slightly odd in the way it was recorded in the sense that although it is a band album, because we were never able to actually all be in the same room at the same time, because of physical limitations, with the exception of one track, "Intermediate Jesus", which was done outside, I tended to demo the tracks to a fairly high level and they would just replace the parts that I'd played on synthesizers with the real thing. So there wasn't a great deal of input from the other guys." Sound In addition to the change in sound coming from it being the first collaborative, full
