Like its predecessor, the tracks from "The Nostalgia Factory" were subsequently released in the band's first studio album "On the Sunday of Life", and the compilation album "Yellow Hedgerow Dreamscape".  Some tracks have been renamed and/or rearranged in later albums and performances.

The album was issued on the band's own "Transmission" label and sold only at shows and through Porcupine Tree's online store, Burning Shed.  An interesting feature of the album is the song "Fadeaway" sung by guest guitarist John Wesley.

Insurgentes (album): Insurgentes is the title of the first full-length solo album released by British musician and record producer Steven Wilson, known for being the founder and frontman of progressive rock band Porcupine Tree.

Grice Peters: Grice Peters (born Martin Charles Grice Peters) aka GRICE, is a London-born English art rock musician, vocalist, lyricist and songwriter.  Grice formed and fronted underground brit-pop flavoured bands 'Laugh like A Madman', 'The burning martyrs', 'The Martyrs', 'SWANSTON' and the avant-garde art rock outfit 'hungersleep' before starting his solo career.  In 2012 he released his debut solo GRICE album PROPELLER which featured renowned saxophonist Raphael Ravenscroft and renowned pedal steel guitarist BJ Cole as well as a number of contributors including Markus Reuter, 05Ric, Luca Calabrese amongst others.  The album was produced by Lee Fletcher and co-produced by Grice.  In 2013 The track 'Highly Strung' was remixed by English synthesizer player, keyboardist and composer Richard Barbieri formerly a member of new wave pioneers Japan and current solo artist and member of progressive rock band Porcupine Tree.

Atlanta (album): Atlanta is a download only double-live album by British progressive rock band Porcupine Tree recorded at the Roxy Theatre, Atlanta, United States on 29 October 2007.  The show recording was initially intended for a prospective Porcupine Tree live album, but this decision was later turned down as development of the "Anesthetize" DVD project began.  In the wake of the news regarding Mick Karn's advanced stage cancer, the band decided to put it out as a downloadable item from the Burning Shed online store at a very cheap cost, as a . RAR file split in two parts, all in MP3 format at 320kbit/s with completely printable artwork designed by Carl Glover.  The profits from the "Atlanta" downloads are intended to help Mick pay his treatment.  A 24-bit FLAC version was released in August 2010; profits from this version go to the Teenage Cancer Trust.  Since the album's artwork and mix is set up for two CDs it is widely considered to be a double album.  The album has a somewhat similar track listing to the "Anesthetize" DVD but includes the first official live recording of the track "A Smart Kid" and some of the songs that were performed at the shows for the Anesthetize shoot, but left out as they were already available on previous live releases (Open Car and Blackest Eyes).

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".
