Question:  The founder and frontman of psychedelic/progressive rock band Porcupine Tree was born in what year?
Context: Anesthetize is the second live DVD by progressive rock band Porcupine Tree, released on 20 May 2010.  The Blu-ray edition was released on 15 June.  It is filmed in high definition and taken from two concerts given by Porcupine Tree at Tilburg, Netherlands on 15 and 16 October, at the end of the "Fear of a Blank Planet" tour in 2008.  The film is directed and edited by Lasse Hoile and the audio track is mixed in stereo and 5.1 Surround by Steven Wilson. In Absentia is the seventh studio album by British progressive rock band Porcupine Tree, first released on 24 September 2002.  The album marked several changes for the band, with it being the first with new drummer Gavin Harrison and the first to move into a more heavy metal and progressive metal direction, contrary to past albums' psychedelic and pop rock sounds.  Additionally, it was their first release on a major record label, Lava Records.  It was very well received critically and commercially, with it often being considered the band's crowning achievement, and selling over triple what any of the band's prior albums had in the past. Steven John Wilson (born 3 November 1967) is an English musician and record producer, most associated with the progressive rock genre.  Currently a solo artist, he became known as the founder, lead guitarist, singer, and songwriter of the band Porcupine Tree, as well as being a member of several other bands.  He has also worked with artists such as Opeth, King Crimson, Pendulum, Jethro Tull, XTC, Yes, Marillion, Tears for Fears, Roxy Music, and Anathema. 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). Moonloop is an EP released by British psychedelic rock and progressive rock band Porcupine Tree, prior to the release of their third studio album, "The Sky Moves Sideways".  It was released on vinyl and CD in the UK by Delerium Records. XMII (also known as Transmission 4.1) is a live-in-studio album by British progressive rock band Porcupine Tree, released in June 2005.  It is the band's second session for XM Satellite Radio and was recorded on 21 July 2003.  Unlike its predecessor, "XM", "XMII" contains mostly tracks from the "Lightbulb Sun" album.  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. Catalogue / Preserve / Amass is a live album released in 2012 by British musician and record producer Steven Wilson, known for being the founder and frontman of psychedelic/progressive rock band Porcupine Tree. Stupid Dream is the fifth studio album by British progressive rock band Porcupine Tree.  It was first released in March 1999, and then re-released on 15 May 2006 due to the band's rising popularity on major record label Lava Records with their releases of "In Absentia" in 2002 and "Deadwing" in 2005.  The album, along with "Lightbulb Sun" in 2000, represented a transitional period for the band, moving away from the band's earlier work in instrumental and psychedelic music, but before they took a more metal direction in 2002 onwards.  The album takes a commercially accessible pop rock sound while still retaining heavy progressive rock influences. 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.  The album was recorded all over the world in studios from Mexico City to Japan and Israel, between January and August 2008, and released in November 2008 as a special deluxe multi disc mail order version, with retail release to follow in February 2009.  According to Wilson himself, the album contained "the most experimental song-based music [he had] made." Storm Corrosion was a musical collaboration between Mikael Åkerfeldt of Swedish progressive metal band Opeth and Steven Wilson, an English solo artist and frontman of the progressive rock band Porcupine Tree.  Åkerfeldt and Wilson began a longstanding musical partnership in 2001 when Wilson produced Opeth's fifth studio album "Blackwater Park".  The two began writing together for a new project in 2010, releasing their self-titled first studio album on May 8, 2012 through Roadrunner Records.
