Problem: 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. By late 1993, however, he wanted to work in a band environment, bringing on frequent collaborators Richard Barbieri as keyboardist, Colin Edwin as bassist, and Chris Maitland as drummer to form the first permanent lineup. With Wilson as lead vocalist and guitarist, this remained the lineup until February 2002, when Maitland left the band and Gavin Harrison was recruited to replace him.

Porcupine Tree originated in 1987 as a collaborative hoax project by Steven Wilson and Malcolm Stocks. Partially inspired by the psychedelic/progressive bands of the 1970s, such as Pink Floyd, that had dominated the music scene during their youth, the two decided to form a fictional legendary rock band named The Porcupine Tree. The two fabricated a detailed back-story including information on alleged band members and album titles, as well as a "colourful" history which purportedly included events such as a meeting at a 1970s rock festival and several trips in and out of prison. As soon as he had put aside enough money to buy his own studio equipment, Wilson obliged this creation with several hours of music to provide "evidence" of its existence. Although Stocks provided a few passages of treated vocals and experimental guitar playing, his role in the project was mostly offering occasional ideas, with the bulk of the material being written, recorded, played, and sung by Wilson. At this point, Porcupine Tree was little more than a joke and a private amusement, as Wilson was concentrating on his other project, No-Man, an endeavour with UK based singer and songwriter Tim Bowness. However, by 1989, he began to consider some of the Porcupine Tree music as potentially marketable. Wilson created an 80-minute-long cassette titled Tarquin's Seaweed Farm under the name of Porcupine Tree. Still showing the spirit of his joke, Wilson included an eight-page inlay which further revealed the hoaxed Porcupine Tree backstory, including references to fictitious band members such as Sir Tarquin Underspoon and Timothy Tadpole-Jones. Wilson sent out copies of Tarquin's Seaweed Farm to several people he felt would be interested in the recordings. Nick Saloman, the cult UK guitarist better known as The Bevis Frond, had suggested that he send one to Richard Allen, a writer for the UK counter-cultural magazine Encyclopaedia Psychedelica and co-editor of the UK psychedelic garage rock magazine Freakbeat. Allen reviewed the tape in both magazines. Whilst he disliked some of the material, he gave much of it a positive review. Several months later, Allen invited Wilson to contribute a track to the double LP A Psychedelic Psauna that was being put together to launch the new Delerium label. Allen would also become the band's manager, press agent, and promoter until 2004, his role in marketing the band's image decreasing after The Sky Moves Sideways album. In the meantime, Wilson had continued to work on new material. In 1990, he released the Love, Death & Mussolini EP, issued in a very limited run of 10 copies. The EP remains an extremely rare, collectible piece. It was composed of nine at-the-time-unreleased tracks, as a preview for the upcoming second album. Later in 1990, Wilson released a second full-length Porcupine Tree cassette called The Nostalgia Factory, which further expanded Porcupine Tree's underground fanbase, although at this point, the band was still carrying on the charade of being 1970s rock legends. By this point, Porcupine Tree was entirely a solo project, with Stocks having amicably moved on to other activities.

What year did Porcupine Tree form?

Problem: Janis Lyn Joplin (; January 19, 1943 - October 4, 1970) was an American rock singer and songwriter; one of the most successful and widely-known female rock stars of her era. After releasing three albums, she died of a heroin overdose at the age of 27. A fourth album, Pearl, was released in January 1971, just over three months after her death.

Joplin appeared at Woodstock starting at approximately 2:00 a.m., on Sunday, August 17, 1969. Joplin informed her band that they would be performing at the concert as if it were just another gig. On Saturday afternoon, when she and the band were flown by helicopter with the pregnant Joan Baez and Baez's mother from a nearby motel to the festival site and Joplin saw the enormous crowd, she instantly became extremely nervous and giddy. Upon landing and getting off the helicopter, Joplin was approached by reporters asking her questions. She referred them to Caserta as she was too excited to speak. Initially Joplin was eager to get on the stage and perform, but was repeatedly delayed as bands were contractually obliged to perform ahead of Joplin. Faced with a ten-hour wait after arriving at the backstage area, Joplin shot heroin and drank alcohol with Caserta, and by the time of reaching the stage, Joplin was "three sheets to the wind". During her performance, Joplin's voice became slightly hoarse and wheezy, and she struggled to dance. Joplin pulled through, however, and engaged frequently with the crowd, asking them if they had everything they needed and if they were staying stoned. The audience cheered for an encore, to which Joplin replied and sang "Ball and Chain". Pete Townshend, who performed with the Who later in the same morning after Joplin finished, witnessed her performance and said the following in his 2012 memoir: "She had been amazing at Monterey, but tonight she wasn't at her best, due, probably, to the long delay, and probably, too, to the amount of booze and heroin she'd consumed while she waited. But even Janis on an off-night was incredible." Janis remained at Woodstock for the remainder of the festival. Starting at approximately 3:00 a.m. on Monday, August 18, Joplin was among many Woodstock performers who stood in a circle behind Crosby, Stills & Nash during their performance, which was the first time anyone at Woodstock ever had heard the group perform with Neil Young. This information was published by David Crosby in 1988. Later in the morning of August 18, Joplin and Joan Baez sat in Joe Cocker's van and witnessed Hendrix's close-of-show performance, according to Baez's memoir And a Voice to Sing With (1989). Still photographs in color show Joplin backstage with Grace Slick the day after Joplin's performance, wherein Joplin appears to be very happy. Joplin was ultimately unhappy with her performance, however, and blamed Caserta. Her singing was not included (by her own insistence) in the 1970 documentary film or the soundtrack for Woodstock: Music from the Original Soundtrack and More, although the 25th anniversary director's cut of Woodstock includes her performance of "Work Me, Lord". The documentary film of the festival that was released to theaters in 1970 includes, on the left side of a split screen, 37 seconds of footage of Joplin and Caserta walking toward Joplin's dressing room tent.

Was her singing not included because she was not happy with her performance at woodstock?
