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.

The Rothschild family is a wealthy family descending from Mayer Amschel Rothschild (1744-1812), a court factor to the German Landgraves of Hesse-Kassel in the Free City of Frankfurt, Holy Roman Empire, who established his banking business in the 1760s. Unlike most previous court factors, Rothschild managed to bequeath his wealth and established an international banking family through his five sons, who established themselves in London, Paris, Frankfurt, Vienna, and Naples. The family was elevated to noble rank in the Holy Roman Empire and the United Kingdom. During the 19th century, the Rothschild family possessed the largest private fortune in the world, as well as the largest private fortune in modern world history.
The Rothschild banking family of the United Kingdom was founded in 1798 by Nathan Mayer Rothschild (1777-1836), who first settled in Manchester but then moved to London. Nathan Mayer von Rothschild, the third son of Mayer Amschel Rothschild (1744-1812), first established a textile jobbing business in Manchester and from there went on to establish N M Rothschild & Sons bank in London.  During the early part of the 19th century, the Rothschild family's London bank took a leading part in managing and financing the subsidies that the British government transferred to its allies during the Napoleonic Wars. Through the creation of a network of agents, couriers and shippers, the bank was able to provide funds to the armies of the Duke of Wellington in Portugal and Spain, therefore funding the war. The providing of other innovative and complex financing for government projects formed a mainstay of the bank's business for the better part of the century. N. M. Rothschild & Sons' financial strength in the City of London became such that, by 1825-26, the bank was able to supply enough coin to the Bank of England to enable it to avert a liquidity crisis.  Nathan Mayer's eldest son, Lionel de Rothschild (1808-1879), succeeded him as head of the London branch. Under Lionel, the bank financed the British government's 1875 purchase of Egypt's interest in the Suez Canal. The Rothschild bank also funded Cecil Rhodes in the development of the British South Africa Company. Leopold de Rothschild (1845-1917) administered Rhodes's estate after his death in 1902 and helped to set up the Rhodes Scholarship scheme at the University of Oxford. In 1873, de Rothschild Freres in France and N. M. Rothschild & Sons of London joined with other investors to acquire the Spanish government's money-losing Rio Tinto copper mines. The new owners restructured the company and turned it into a profitable business. By 1905, the Rothschild interest in Rio Tinto amounted to more than 30 percent. In 1887, the French and British Rothschild banking houses loaned money to, and invested in, the De Beers diamond mines in South Africa, becoming its largest shareholders.  The London banking house continued under the management of Lionel Nathan de Rothschild (1882-1942) and his brother Anthony Gustav de Rothschild (1887-1961), and then to Sir Evelyn de Rothschild (b. 1931). In 2003, following Sir Evelyn's retirement as head of N. M. Rothschild & Sons of London, the British and French financial firms merged under the leadership of David Rene de Rothschild.

Which Rothschilds ran the British banks?
Lionel de Rothschild (1808-1879), succeeded him as head of the London branch.
