Some context: Vladimir Vladimirovich Nabokov (; Russian: Vladimir Vladimirovich Nabokov, pronounced [vla'djimjIr na'bok@f] ( listen), also known by the pen name Vladimir Sirin; 22 April [O.S. 10 April] 1899 - 2 July 1977) was a Russian-American novelist, translator and entomologist.
Nabokov's interest in entomology had been inspired by books of Maria Sibylla Merian he had found in the attic of his family's country home in Vyra. Throughout an extensive career of collecting he never learned to drive a car, and he depended on his wife Vera to take him to collecting sites. During the 1940s, as a research fellow in zoology, he was responsible for organizing the butterfly collection of the Museum of Comparative Zoology at Harvard University. His writings in this area were highly technical. This, combined with his specialty in the relatively unspectacular tribe Polyommatini of the family Lycaenidae, has left this facet of his life little explored by most admirers of his literary works. He described the Karner blue. The genus Nabokovia was named after him in honor of this work, as were a number of butterfly and moth species (e.g. many species in the genera Madeleinea and Pseudolucia bear epithets alluding to Nabokov or names from his novels). In 1967, Nabokov commented: "The pleasures and rewards of literary inspiration are nothing beside the rapture of discovering a new organ under the microscope or an undescribed species on a mountainside in Iran or Peru. It is not improbable that had there been no revolution in Russia, I would have devoted myself entirely to lepidopterology and never written any novels at all."  The palaeontologist and essayist Stephen Jay Gould discussed Nabokov's lepidoptery in his essay, "No Science Without Fancy, No Art Without Facts: The Lepidoptery of Vladimir Nabokov" (reprinted in I Have Landed). Gould notes that Nabokov was occasionally a scientific "stick-in-the-mud". For example, Nabokov never accepted that genetics or the counting of chromosomes could be a valid way to distinguish species of insects, and relied on the traditional (for lepidopterists) microscopic comparison of their genitalia.  The Harvard Museum of Natural History, which now contains the Museum of Comparative Zoology, still possesses Nabokov's "genitalia cabinet", where the author stored his collection of male blue butterfly genitalia. "Nabokov was a serious taxonomist," says museum staff writer Nancy Pick, author of The Rarest of the Rare: Stories Behind the Treasures at the Harvard Museum of Natural History. "He actually did quite a good job at distinguishing species that you would not think were different--by looking at their genitalia under a microscope six hours a day, seven days a week, until his eyesight was permanently impaired." The rest of his collection, about 4,300 specimens, was given to the Lausanne's Museum of Zoology in Switzerland.  Though his work was not taken seriously by professional lepidopterists during his life, new genetic research supports Nabokov's hypothesis that a group of butterfly species, called the Polyommatus blues, came to the New World over the Bering Strait in five waves, eventually reaching Chile.  Many of Nabokov's fans have tried to ascribe literary value to his scientific papers, Gould notes. Conversely, others have claimed that his scientific work enriched his literary output. Gould advocates a third view, holding that the other two positions are examples of the post hoc ergo propter hoc fallacy. Rather than assuming that either side of Nabokov's work caused or stimulated the other, Gould proposes that both stemmed from Nabokov's love of detail, contemplation, and symmetry.

Some context: Feeder are a Welsh rock band formed in Newport, Wales. They have released ten studio albums, twelve compilations, four EPs, and 40 singles. They have spent a total of 182 weeks on the singles and albums charts combined as of 2017, and have accumulated 25 top 75 singles between 1997 and 2012. At their peak of commercial success, Feeder won two Kerrang!
After building a strong fanbase with the release of Swim, the band released their first full-length album in 1997. The result Polythene, was one of the most critically acclaimed albums of 1997 with Metal Hammer and Kerrang!, placing the album at first and sixth in their respective end of year lists. Kerrang! later included the album in their 200 Albums For the Year 2000 list in the "Essential Britrock" category. Two tracks from Swim were used for the album, being "Descend" and "Stereoworld".  After the recording sessions were completed, the album's first single "Tangerine" was released and charted at #60 in the UK singles chart. This was followed by "Cement", charting at #53 and then the release of the album which charted at #65. Two more singles were released before and after their main stage debut at the Reading festival, with "Crash" making number #48, while "High" charted at number #24.  The album as of May 2017, has sold 100,000 copies, certifying the album Gold twenty years after its original release. They also re-issued the album in October 1997, with "High" included and the "Stereo World" b-side "Change" replacing "Waterfall" from the original track list. Also included as an enhanced element was the video for "High". The album caused many critics to label the band "The UK's answer to the Smashing Pumpkins", and also draw comparisons to The Pixies and Talk Talk.  In early 1998, following the band's final 1997 tour in support of Polythene, the band travelled to the United States as a support act for Everclear. During their U.S. tour, the band released a re-worked version of "Suffocate" for UK release, which charted at #37. After their return to the UK, they played their own headline tour with Everclear this time in the supporting position. Later that year, Feeder started to play various music festivals in the United States, alongside a headline tour with "High" being released to radio stations and charting at #24 on the Billboard Modern Rock Tracks chart; it was the follow-up to "Cement" which had charted at #31, also on the same listing. During the band's first U.S. tour, Grant broke his ankle and picked up other injuries, while finding it hard to sleep at nights. This inspired him to write "Insomnia", which later appeared on their second album. They stayed in the U.S. for the majority of the year, with a trip back to the UK for their V98 appearance. Feeder later included live-only guitarist Dean Tidey; Grant once said in an interview with Kerrang!, that he was considering bringing in another guitarist for their live gigs.
