The Fourth World refers to

Fourth World follows the First World, Second World, and Third World hierarchy of nation-state status; however, unlike the former categories, Fourth World is not spatially bounded, and is usually used to refer to populations whose size and shape does not map onto citizenship in a specific nation-state. It can denote nations without a sovereign state, emphasising the non-recognition and exclusion of ethnically- and religiously-defined peoples from the politico-economic world system, e.g. the Romani people worldwide, the Basque, Sami, pre-First World War Ashkenazi Jews in the Pale of Settlement, the Assyrians, and the Kurds in the Middle East, Pashtun throughout Afghanistan and Pakistan, the indigenous peoples of the Americas and First Nations groups throughout North, Central and South America, and indigenous Africans and Asians. Spanish sociologist Manuel Castells of the University of Southern California Annenberg School for Communication has made extensive use of the term fourth world'.

Flora Purim (born March 6, 1942 in Rio de Janeiro) is a Brazilian jazz singer known primarily for her work in the jazz fusion style. She became prominent for her part in Chick Corea's landmark album Return to Forever. She has recorded and performed with numerous critically acclaimed artists, including Stanley Clarke, Chick Corea, Dizzy Gillespie, Gil Evans, Stan Getz, the Grateful Dead, Santana, Jaco Pastorius, and her husband Airto Moreira.

In 2002, Purim was the recipient of one of Brazil's highest awards; the 2002 Ordem do Rio Branco for Lifetime Achievement.

Purim's parents were both classical musicians, her Romanian-born father played violin and her Brazilian mother was a pianist. Flora discovered American jazz when her mother played it while her husband was out of the house.

"She would bring home those 78 vinyl RPMs and when my father was at work, she would play them. That was how I got exposed to jazz music... basically listening to Dinah Washington, Billie Holiday, and Frank Sinatra. But also a lot of piano players, such as Bill Evans, Oscar Peterson and Errol Garner, those were my mother's favorites."

Dee Dee Bridgewater (born May 27, 1950) is an American Jazz singer. She is a three-time Grammy Award winning singer-songwriter, as well as a Tony Award - winning stage actress and host of National Public Radio's syndicated radio show JazzSet with Dee Dee Bridgewater. She is a United Nations Ambassador for the Food and Agriculture Organization.

Born Denise Eileen Garrett in Memphis, Tennessee, she grew up in Flint, Michigan. Her father, Matthew Garrett, was a jazz trumpeter and teacher at Manassas High School, and through his playing, Denise was exposed to jazz early on. At the age of sixteen, she was a member of a rock and rhythm'n'blues trio, singing in clubs in Michigan. At 18, she studied at the Michigan State University before she went to the University of Illinois at Urbana-Champaign. With their jazz band, she toured the Soviet Union in 1969. The next year, she met trumpeter Cecil Bridgewater, and after their marriage, they moved to New York City, where Cecil played in Horace Silver's band.

Dee Dee Ramone (born Douglas Glenn Colvin) (September 18, 1951 – June 5, 2002) was an American songwriter and musician, best known as founding member, songwriter, and bassist for punk rock band the Ramones.

Though nearly all of the Ramones' songs were credited equally to all the band members, Dee Dee was the band's most prolific lyricist and songwriter, writing many of the band's most well-known songs, such as "53rd & 3rd", "Commando", "Rockaway Beach", and "Poison Heart". He was initially the band's lead vocalist, though his (then) inability to sing and play bass at the same time resulted in original drummer Joey Ramone taking over the lead vocalist duties. Dee Dee would serve as the band's bassist and songwriter from 1974 through 1989, when he left to pursue a short-lived career in hip hop music under the name Dee Dee King. He soon returned to his punk roots and released three solo albums featuring brand new songs, many of which were later recorded by the Ramones. He toured the world playing his new songs, Ramones songs and some old favorites in small clubs, and continued to write songs for the Ramones until 1996, when the band officially retired.
