input: While holidaying with her family in December 1920, Heyer met George Ronald Rougier, who was two years her senior. The two became regular dance partners while Rougier studied at the Royal School of Mines to become a mining engineer. In the spring of 1925, shortly after the publication of her fifth novel, they became engaged. One month later, Heyer's father died of a heart attack. He left no pension, and Heyer assumed financial responsibility for her brothers, aged 19 and 14. Two months after her father's death, on 18 August, Heyer and Rougier married in a simple ceremony.  In October 1925 Rougier was sent to work in the Caucasus Mountains, partly because he had learned Russian as a child. Heyer remained at home and continued to write. In 1926, she released These Old Shades, in which the Duke of Avon courts his own ward. Unlike her first novel, These Old Shades focused more on personal relationships than on adventure. The book appeared in the midst of the 1926 United Kingdom general strike; as a result, the novel received no newspaper coverage, reviews, or advertising. Nevertheless, the book sold 190,000 copies. Because the lack of publicity had not harmed the novel's sales, Heyer refused for the rest of her life to promote her books, even though her publishers often asked her to give interviews. She once wrote to a friend that "as for being photographed at Work or in my Old World Garden, that is the type of publicity which I find nauseating and quite unnecessary. My private life concerns no one but myself and my family."  Rougier returned home in the summer of 1926, but within months he was sent to the East African territory of Tanganyika. Heyer joined him there the following year. They lived in a hut made of elephant grass located in the bush; Heyer was the first white woman her servants had ever seen. While in Tanganyika, Heyer wrote The Masqueraders; set in 1745, the book follows the romantic adventures of siblings who pretend to be of the opposite sex in order to protect their family, all former Jacobites. Although Heyer did not have access to all of her reference material, the book contained only one anachronism: she placed the opening of White's a year too early. She also wrote an account of her adventures, titled "The Horned Beast of Africa", which was published in 1929 in the newspaper The Sphere.  In 1928, Heyer followed her husband to Macedonia, where she almost died after a dentist improperly administered an anaesthetic. She insisted they return to England before starting a family. The following year Rougier left his job, making Heyer the primary breadwinner. After a failed experiment running a gas, coke, and lighting company, Rougier purchased a sports shop in Horsham with money they borrowed from Heyer's aunts. Heyer's brother Boris lived above the shop and helped Rougier, while Heyer continued to provide the bulk of the family's earnings with her writing.

Question: The Gathering is a Dutch rock band, founded in 1989 by brothers Hans and Rene Rutten and vocalist Bart Smits in Oss, North Brabant. The Gathering earliest releases were categorized as atmospheric doom metal with influences from death metal acts like Celtic Frost and Hellhammer. In 1998 with the release of their 5th studio album, How to measure a planet?, they had a major shift in musical style, with the group acknowledging the growing influence of shoegazing, post-rock, experimental rock and the more ethereal sounds of 4AD bands, such as Dead Can Dance, Cocteau Twins, as well as Pink Floyd and Massive Attack; they expanded their sound, which acquired characteristics of progressive, alternative rock, and trip hop and gained success and recognition beyond the European borders. The group continue to expand upon the experimental nature of their music.

Founded by brothers Hans and Rene Rutten and vocalist Bart Smits, The Gathering formed in the city of Oss, North Brabant, Netherlands in 1989. Soon after they were joined by Hugo Prinsen Geerligs, Jelmer Wiersma and Frank Boeijen to complete their first line-up. The Gathering's earliest recordings were categorized as atmospheric doom metal with influences from death metal acts like Celtic Frost and Hellhammer.  In 1990 they recorded a demo tape entitled An Imaginary Symphony which met some positive reactions from the underground metal scene due to their unusual use of keyboards in metal-oriented music. A second demo, "Moonlight Archer" was recorded in April 1991, was picked up by several music journalists. Both demos suffered from poor production; however they did help establish the band's name on the live circuit opening for bands such as Deadhead, Invocator, Samael, Morbid Angel and Death.  After signing with Foundation 2000, the group released their debut album Always... in 1992. On this album, Bart Smits was accompanied by Marike Groot on vocals, who also joined The Gathering on stage for most of the gigs. the album was a minor success on the European continent, where it went on to shift nearly 20,000 units over the next few years. In 1992 both Bart Smits and Marike Groot decided to leave the group due to musical differences; the other members wanted to change direction towards a lighter, more progressive sound. Smits went on to form his own project, called Wish, to explore a darker, heavier sound.  In 1993 the group recruited two new vocalists, Niels Duffhues and female counterpart Martine van Loon. A second album, Almost a Dance, was recorded and released in 1993 by Foundation 2000. The album was met with much criticism aimed at Duffhues' punk-ish tone being decidedly out of step with the music, and the album was largely written off as a result. The group collectively acknowledged their disappointments with Almost a Dance and decided to start writing new material and start the search for a new vocalist.
