Ange is a French progressive rock band formed in September 1969 by the Décamps brothers, Francis (keyboards) and Christian (vocals, accordion, acoustic guitar and keyboards).

Ange was initially influenced by Genesis and King Crimson, and its music was quite theatrical and poetic. Its first success in France was the cover of a Jacques Brel song, Ces gens-là, on its second album Le Cimetière des Arlequins. The band provided its first concert on January 30, 1970 at the cultural center "La Pépinière", in Belfort, France. It performed 110 concerts in England from 1973 to 1976, opening for Genesis at the Reading Festival in England, on August 26, 1973, fronting some 30.000 listeners.

One of the reasons for which the band was unable to break through into the British market was because they sang in French. Ange eventually released an English-speaking version of its fifth album Par les fils de Mandrin (By the sons of Mandrin), which sold poorly and is hard to find, although this version has since been made available on CD. Unfortunately, after three albums, the quality of creation had started to decrease, and Par les fils de Mandrin was probably not a good choice to try to break into the British market. Au delà du délire, third album, could be the band's best effort and is recommended as the one to listen to as a starter, for newcomers to the Ange progressive phenomenon.

Detroit ( /diˈtrɔɪt/) is the largest city in the U.S. state of Michigan, and the seat of Wayne County. It is the major city among the primary cultural, financial, and transportation centers in the Metro Detroit area, a region of 5.2 million people, and serves as a major port on the Detroit River connecting the Great Lakes system to the Saint Lawrence Seaway. It was founded on July 24, 1701, by the French explorer, adventurer, and nobleman Antoine de la Mothe, sieur de Cadillac.

In 2010, the city had a population of 713,777 and ranked as the 18th most populous city in the United States. The name Detroit sometimes refers to the Metro Detroit area with a population of 4,296,250 for the six-county Metropolitan Statistical Area, the United States' eleventh-largest, and a population of 5,218,852 for the nine-county Combined Statistical Area as of the 2010 Census.
