Other Music is a music retail store that sells CDs and records through their website as well as a brick-and-mortar store in Manhattan.
 It specializes in the sale of closely curated underground, rare and experimental music.
 The physical store is located at 11-13 East 4th Street, in Greenwich Village, in lower Manhattan, in New York City, New York, U.S.A.
Iztacalco (   ) is one of the 16 "delegaciones" (boroughs) into which Mexico's Federal District is divided.
 It is located in the center-east of the district and is the smallest of the city’s boroughs.
 The area’s history began in 1309 when the island of Iztacalco, in what was Lake Texcoco, was settled in 1309 by the Mexica who would later found Tenochtitlan, according to the Codex Xolotl.
 The island community would remain small and isolated through the colonial period, but drainage projects in the Valley of Mexico dried up the lake around it.
 The area was transformed into a maze of small communities, artificial islands called chinampas and solid farmland divided by canals up until the first half of the 20th century.
 Politically, the area has been reorganized several times, with the modern borough coming into existence in 1929.
 Today, all of the canals and farmland are dried out and urbanized as the most densely populated borough and the second most industrialized.
Manhattan ( , ) is the most densely populated borough of New York City, its economic and administrative center, and its historical birthplace.
 Locally it is often referred to simply as "The City".
 The borough is coextensive with New York County, founded on November 1, 1683, as one of the original counties of the U.S. state of New York.
 The borough consists mostly of Manhattan Island, bounded by the Hudson, East, and Harlem rivers; several small adjacent islands; and Marble Hill, a small neighborhood now on the U.S. mainland, physically connected to the Bronx and separated from the rest of Manhattan by the Harlem River.
Jammyland Records was an independent music retailer in New York City.
 It opened in 1993 at its location on 60 E 3rd Street in Manhattan, by owner Ira Heaps.
 The store specialized in Jamaican music, specifically the ska, rocksteady and reggae genres of the 60s and 70s recorded on vinyl, though it also sold CDs.
 Jammyland also reissued more obscure reggae.
 The store used to have a recording studio in its basement, where artists including Victor Rice, The Slackers and the Dynamos recorded, but later an avant-garde/noise music retailer opened in the basement.
The Bronx ( ) is the northernmost of the five boroughs of New York City, within the U.S. state of New York.
 It is geographically south of Westchester County; north and east of the island and borough of Manhattan to the south and west across the Harlem River; and north of the borough of Queens, across the East River.
 Of the five boroughs, the Bronx is the only one that has the majority of its area on the U.S. mainland and, with a land area of 42 sqmi and a population of 1,455,720 in 2016, has the fourth-largest land area, the fourth-highest population, and the third-highest population density.
 Since 1914, the Bronx has had the same boundaries as Bronx County, a county of New York and the third most densely populated county in the United States.
The City of New York, often called New York City or simply New York, is the most populous city in the United States.
 With an estimated 2016 population of 8,537,673 distributed over a land area of about 302.6 sqmi , New York City is also the most densely populated major city in the United States.
 Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world.
 A global power city, New York City exerts a significant impact upon commerce, finance, media and entertainment, art, fashion, research, technology, education, politics, and sports, its fast pace defining the term "New York minute".
 Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural, financial, and media capital of the world.
Manhattanization is a neologism coined to describe the construction of many tall or densely situated buildings, which transforms the appearance and character of a city to resemble Manhattan, a heavily and densely populated borough of New York City.
 It was a pejorative word used by critics of the highrise buildings built in San Francisco during the 1960s and 1970s, who claimed the skyscrapers would block views of the bay and the surrounding hills.
 With careful urban planning, the phenomenon became more accepted in time.
 The term also gained usage as a buzzword for high-density developments in Las Vegas, Nevada, Los Angeles, Dubai, and Miami in the early 2000s and again in the 2010s.
 Another example is the construction boom in Toronto since 2007.
 The term has even been applied to many smaller US cities that have seen a large spike in downtown high rise rental buildings since the year 2000.
 Nonetheless, these cities would have to multiply their populations many times over to match the population density of Manhattan, though this is a biased comparison between a city and a district, as even the other four "outer boroughs" of New York City would have to nearly triple in population to match Manhattan's current density.
 Likewise, the just over 1 sqmi Brickell (Miami) financial district is more dense than New York City overall.
Queens is the easternmost and largest in area of the five boroughs of New York City.
 It is geographically adjacent to the borough of Brooklyn at the southwestern end of Long Island, and to Nassau County farther east on Long Island; in addition, Queens shares water borders with the boroughs of Manhattan and the Bronx.
 Coterminous with Queens County since 1899, the borough of Queens is the second-largest in population (after Brooklyn), with a census-estimated 2,333,054 residents in 2016, approximately 48% of them foreign-born.
 Queens County also is the second-most populous county in the U.S. state of New York, behind the neighboring borough of Brooklyn, which is coterminous with Kings County.
 Queens is the fourth-most densely populated county among New York City's boroughs, as well as in the United States.
 If each of New York City's boroughs were an independent city, Queens also would be the nation's fourth most populous, after Los Angeles, Chicago, and Brooklyn.
 Queens is the most ethnically diverse urban area in the world.
Brooklyn ( ) is the most populous borough of New York City, with a Census-estimated 2,629,150 residents in 2016.
 It borders the borough of Queens at the southwestern end of Long Island, and has several bridge connections to the nearby boroughs of Staten Island and Manhattan.
 Since 1896, Brooklyn has had the same boundaries as Kings County, the most populous county in the U.S. state of New York and the second-most densely populated county in the United States, after the county of New York (which is coextensive with the borough of Manhattan).
