Question: Were Porcupine Tree and Skinny Puppy formed in the same year?

Context paragraphs:
OhGr: ohGr is a industrial band formed by Nivek Ogre and Mark Walk of Skinny Puppy.  Early ohGr releases incorporated hip hop and synthpop influences, and in contrast to Skinny Puppy, utilized conventional structures and a lighter tone.  Ogre noted that this direction was inspired by the pop bands he enjoyed as a child, such as The Archies.  However, from "Devils in my Details" onwards, ohGr has taken to a more abrasive, non-linear flavour of electro-industrial.

Nivek Ogre: Nivek Ogre (born Kevin Graham Ogilvie December 5, 1962) is a Canadian musician, performance artist and actor best known as a founding member of the industrial music group Skinny Puppy.  Since that band featured another Kevin (Crompton, a.k.a. cEvin Key) and was produced by another Ogilvie (Dave, a.k.a. Rave), Ogre's alias was practical as well as theatrical.  Since 1982, he has served as Skinny Puppy's primary lyricist and vocalist, occasionally providing instrumentation and samples.  Ogre's guttural singing style and use of costumes, props, and fake blood on stage helped to bring Skinny Puppy extensive publicity and has inspired numerous other musicians.

Doubting Thomas (band): Doubting Thomas is an industrial band formed by two members of Skinny Puppy: cEvin Key and the late Dwayne Goettel.  It is considered a Skinny Puppy side project; nearly all their music is instrumental.  The band shares its name with an American roots band, to whom they have no relation.

Porcupine Tree: Porcupine Tree were an English rock band formed by musician Steven Wilson in 1987.  The band began essentially as a solo project for Wilson, who created all of the band's music.  However, by 1993, Wilson desired to work in a band environment, and so brought on frequent collaborators Richard Barbieri on keyboards, Colin Edwin on bass and Chris Maitland on drums as permanent band members.  With Wilson still in charge of guitar and lead vocals, this would remain the lineup until 2001, when the band recruited Gavin Harrison to replace Maitland on drums.

List of Skinny Puppy side projects: This is a list of side projects of the prominent industrial band Skinny Puppy, who have released twelve albums and toured extensively since 1982.  This list includes other projects begun by cEvin Key and Nivek Ogre—the only constant members of Skinny Puppy—since its inception.  Other members have included Dwayne Goettel, Mark Walk, Dave "Rave" Ogilvie, and many other guests/session musicians; this list does not include other projects of those musicians.

Tenebrae Vision: Tenebrae Vision is the only album of Canadian industrial band Cyberaktif which consisted of cEvin Key and Dwayne R. Goettel of Skinny Puppy and former Skinny Puppy member Bill Leeb of Front Line Assembly.  For "Cyberaktif", Leeb adopted his stage name, Wilhelm Schroeder, he had used while with Skinny Puppy.  The album was released in 1991 through Wax Trax!  and features Blixa Bargeld of German industrial band Einstürzende Neubauten.

Download (band): Download is a Canadian electronic music group formed by Dwayne Goettel and cEvin Key of Skinny Puppy in 1994.  The initial lineup also included Off & Gone's Phil Western and Mark Spybey of Dead Voices on Air, but has since been particularly fluid, with Key and Western being the only constant members following Goettel's death.  Download's music has been described as post-industrial, drawing from the band's genesis as part of Skinny Puppy but also sharing common stylistic ground with such artists as Aphex Twin and Autechre.  The primary instrumentation common throughout their albums is a blend of synthesizers and sampled instruments; the music is particularly centered on elements of percussion and rhythm.

Tarquin's Seaweed Farm: Tarquin's Seaweed Farm, subtitled "Words from a Hessian Sack", is the first album to be released by Steven Wilson under the name "Porcupine Tree".  It was originally a compiled cassette of experimental music made by Steven Wilson for his joke band he formed with his friend Malcom Stocks.  The cassette was only sent out to a few people, but was enough to give the band a bit of fame in the UK underground music scene of the time, being picked up by the underground magazine Freakbeat.  It was later released under Delerium Records in 1991 in a limited edition of 300 copies.  Eventually, the tracks from this and the later Porcupine Tree album "The Nostalgia Factory" were compiled into what are considered Porcupine Tree's first true studio albums, "On the Sunday of Life" and "Yellow Hedgerow Dreamscape".

Skinny Puppy: Skinny Puppy is a Canadian industrial music group formed in Vancouver, British Columbia in 1982.  The group is widely considered to be one of the founders of the electro-industrial genre.  Initially envisioned as an experimental side project by cEvin Key (Kevin Crompton) while he was in the new wave band Images in Vogue, Skinny Puppy evolved into a full-time project with the addition of vocalist Nivek Ogre (Kevin Ogilvie).  Over the course of a dozen studio albums and many live tours, Key and Ogre have been the only constant members.  Other members have included Dwayne Goettel (1986–1995), Dave "Rave" Ogilvie (long-time associate, producer, and "unofficial" fourth member until 1995), Mark Walk (2003–present), and a number of guests, including Bill Leeb (1985–1986, under the pseudonym Wilhelm Schroeder), Al Jourgensen (1989), and many others.

CEvin Key: cEvin Key (born Kevin William Crompton, February 13, 1961) is a Canadian musician and founding member of the industrial music band Skinny Puppy.  In addition to his work with Skinny Puppy, Key has had several side projects, including Doubting Thomas, Cyberaktif, and Hilt.  After Skinny Puppy disbanded in 1995, Key's main project was electronic noise group Download, as well as some solo releases.
