The Niger River ( /ˈnaɪdʒər/ NY-jər) is the principal river of western Africa, extending about 4,180 km (2,600 mi). Its drainage basin is 2,117,700 km² (817,600 sq mi) in area. Its source is in the Guinea Highlands in southeastern Guinea. It runs in a crescent through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta or the Oil Rivers, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded only by the Nile and the Congo River (also known as the Zaïre River). Its main tributary is the Benue River.

The Niger is called Jeliba or Joliba "great river" in Manding; Orimiri or Orimili "great water" in Igbo; Egerew n-Igerewen "river of rivers" in Tuareg; Isa Ber "big river" in Songhay; Kwara in Hausa; and Oya in Yoruba. The origin of the name Niger, which originally applied only to the middle reaches of the river, is uncertain. The likeliest possibility is an alteration, by influence of Latin niger "black", of the Tuareg name egerew n-igerewen, which is used along the middle reaches of the river around Timbuktu. As Timbuktu was the southern end of the principal Trans-Saharan trade route to the western Mediterranean, it was the source of most European knowledge of the region.

Niger (French pronunciation: [niʒɛʁ], but occasionally pronounced as /niːˈʒɛər/ or ⁱ/ˈnaɪdʒər/), officially the Republic of Niger, is a landlocked country in Western Africa, named after the Niger River. It borders Nigeria and Benin to the south, Burkina Faso and Mali to the west, Algeria and Libya to the north and Chad to the east. Niger covers a land area of almost 1,270,000 km², making it the largest nation in West Africa, with over 80 percent of its land area covered by the Sahara desert. The country's predominantly Islamic population of just above 15,000,000 is mostly clustered in the far south and west of the nation. The capital city is Niamey, located in the far southwest corner of Niger.

Niger is a developing country, and consistently ranks as one of the lowest ranks of the United Nations' Human Development Index (HDI), 186th of 187 countries in 2011. Much of the non-desert portions of the country are threatened by periodic drought and desertification. The economy is concentrated around subsistence and some export agriculture clustered in the more fertile south, and the export of raw materials, especially uranium ore. Niger remains handicapped by its landlocked position, desert terrain, poor education and poverty of its people, lack of infrastructure, poor health care, and environmental degradation.

Roy Ayers (born September 10, 1940) is an American funk, soul, and jazz composer and vibraphone player. Ayers began his career as a post-bop jazz artist, releasing several albums with Atlantic Records, before his tenure at Polydor Records beginning in the 1970s, during which he helped pioneer jazz-funk .

Ayers was born in Los Angeles, California and grew up in a musical family. At the age of five, Lionel Hampton gave him his first pair of vibraphone mallets. The area of Los Angeles that Ayers grew up in, now known as "South Central", but then known as "South Park", was the epicenter of the Southern California Black Music Scene. The schools Roy attended (Wadsworth Elementary, Nevins Middle School, and Thomas Jefferson High School) were all close to the famed Central Avenue, Los Angeles' equivalent of Harlem's Lenox Avenue and Chicago's State Street. Roy would likely have been exposed to music as it not only emanated from the many nightclubs and bars in the area, but also poured out of many of the homes where the musicians who kept the scene alive lived in and around Central. His high school, Thomas Jefferson High School, produced some of the most talented new musicians, such as Dexter Gordon.

Lowell "Sly" Fillmore Dunbar (born 10 May 1952,Kingston, Jamaica) is a drummer.

Dunbar, whose nickname was reportedly given for his passion for Sly & the Family Stone, launched his musical career while still in his adolescence, playing with a local group, The Yardbrooms, at the age of fifteen. His recording debut was in 1969, when he appeared on an album, Double Barrel, by Dave and Ansell Collins. Dunbar subsequently continued to play with Ansell Collins in a band, Skin, Flesh and Bones.

Meeting Robbie Shakespeare in 1972, then playing the bass guitar for The Hippy Boys, Dunbar began a lifelong friendship. When Shakespeare was asked to recommend a drummer for a recording session for producer Bunny Lee's The Aggrovators, he remembered Dunbar. Following the session, Dunbar and Shakespeare agreed to keep working together. Their first break came when they accompanied Peter Tosh on his album, Legalize It (1976). The duo continued to play with Tosh's band until 1979, recording four additional albums — Equal Rights, Bush Doctor, Mystic Man and Wanted Dread and Alive and producing Tosh's hit duet with Mick Jagger, "(Keep On Walking) Don't Look Back)" (1978).
