"Mannenberg" is a Cape jazz song by South African musician Abdullah Ibrahim, first recorded in 1974. Driven into exile by the apartheid government, Ibrahim had been living in Europe and the United States during the 1960s and '70s, making brief visits to South Africa to record music. After a successful 1974 collaboration with producer Rashid Vally and a band that included Basil Coetzee and Robbie Jansen, Ibrahim began to record another album with these three collaborators and a backing band assembled by Coetzee. The song was recorded during a session of improvisation, and includes a saxophone solo by Coetzee, which led to him receiving the sobriquet "Manenberg".

The piece incorporates elements of several other musical styles, including marabi, ticky-draai, and langarm, and became a landmark in the development of the genre of Cape jazz. The song has been described as having a beautiful melody and catchy beat, conveying themes of "freedom and cultural identity." It was released under Ibrahim's former name Dollar Brand on the 1974 vinyl album Mannenberg – Is Where It's Happening. Named after the township of Manenberg, it was an instant hit, selling tens of thousands of copies within a few months of its release. It later became identified with the struggle against apartheid, partly due to Jansen and Coetzee playing it at rallies against the government, and was among the movement's most popular songs in the 1980s. The piece has been covered by other musicians, and has been included on several jazz collections.

Abdullah Ibrahim was born in Cape Town in 1934. Before his conversion to Islam in 1968, he was known as "Dollar Brand". He had a mixed racial heritage, making him a Coloured person according to the South African government. His mother played piano in a church and the style of the hymnal music she played would remain an influence on Ibrahim. In addition, he learned to play several genres of music during his youth in Cape Town, including marabi, mbaqanga, and American jazz. He became well known in jazz circles in Cape Town and Johannesburg, and in 1959, along with Kippie Moeketsi, Hugh Masekela, Jonas Gwangwa, Johnny Gertze, and Makaya Ntshoko, formed the mixed-race group The Jazz Epistles. Although the group avoided explicitly political activity, the apartheid government was suspicious of it and other jazz groups, and targeted them heavily during the increase in state repression following the Sharpeville massacre. The Epistles broke up, and in 1962 Ibrahim went into exile. In the 1960s and '70s, Ibrahim and his wife Sathima Bea Benjamin largely lived in exile in Europe and the United States, returning to South Africa only for brief periods of time. He lived for a while in New York City, playing with the band of Duke Ellington and learning composition at the Juilliard School of Music. As the Black Power movement developed in the 1960s and 1970s, it influenced a number of Ibrahim's friends and collaborators, who began to see their music as a form of cultural nationalism. Ibrahim in turn began to incorporate African elements into his jazz.

The piece was created while the apartheid government of South Africa was forcibly removing Coloured families from their homes as part of the destruction of District Six; this destruction of a neighbourhood that was "a symbol of resilience and creativity in the face of racial oppression" influenced Ibrahim's music. Ibrahim met Rashid Vally at the latter's Johannesburg record shop, Kohinoor, in the early 1970s. Vally produced two of Ibrahim's albums in the following years. The pair produced a third album in 1974, titled Underground in Africa, in which Ibrahim abandoned his financially unsuccessful folk-infused jazz of the previous albums. The new album was instead a fusion of jazz, rock music, and South African popular music; it sold much better than Ibrahim's previously collaborations with Vally. While recording Underground, Ibrahim collaborated with Oswietie, a local band of which Robbie Jansen and Basil Coetzee were saxophonists, and who played a large role in creating the album's fusion style. After the success of Underground, Ibrahim asked Coetzee to bring together a supporting band for his next recording: the group Coetzee put together included Jansen, as well as others who had not worked on Underground.

"Mannenberg" was recorded in June 1974 during one of Ibrahim's visits to South Africa, in a studio in Cape Town, and was produced by Rashid Vally on his new label As-Shams (the name suggested by Ibrahim, meaning in Arabic "The Sun"). The track was recorded after Ibrahim began improvising at the piano, and gradually asked the rest of the band to join in; although Ibrahim made suggestions about the melody, the piece also contained collective improvisation. The piece was made after a few days of recording previously composed music; it was recorded quickly — Ibrahim recalled in 2014 that it took only one take. Asked in an interview how the title came about, he said: "Because Basil was from Manenberg and for us Manenberg was just symbolic of the removal out of District Six, which is actually the removal of everybody from everywhere in the world, and Manenberg specifically because ... it signifies, it's our music, and it's our culture ..." The township of Manenberg was considered symbolic with respect to apartheid in the same way as Soweto. The track was released on the album Mannenberg – Is Where It's Happening in the same year. The album only featured two songs; "Mannenberg", and "The Pilgrim" (which was similarly long, at 12 minutes and 47 seconds). The title "Mrs. Williams from Mannenberg", in reference to Gladys Williams, former housekeeper of one of the musicians, Morris Goldberg, was also considered for the album, and a photograph of her by Ibrahim was used on the album cover.

"Mannenberg" has a "lilting melody" with a "gentle, hypnotic groove". The song has been described as an example of the use of purely musical techniques to convey subversive messages. The piece has no lyrics, but drew on a number of aspects of Black South African culture, including church music, jazz, marabi, and blues, to create a piece that conveyed a sense of freedom and cultural identity. It includes a saxophone solo by Coetzee, whose role in the song earned him his nickname "Manenberg". During the recording, the piano played by Ibrahim had thumbtacks attached to the hammers; the instrument thus had a "metallic timbre" that was generally associated with marabi music. Jazz pianist Moses Molelekwa would later state that "Mannenberg" was "a dance song, a party song [like] most of the jazz that was coming out at that period." Commentator John Edwin Mason would write that, "It had an irresistible hook—its beautiful melody. It was driven by an infectious, danceable beat." The popularity of the piece was also attributed to the fact that it contained elements of many musical styles, thus sounding familiar to a large number of listeners: the groove of the piece incorporated elements of marabi, the beat was similar to that of ticky-draai, and the saxophone melody drew from langarm, while all of it was based on an "underlying aesthetic" of jazz. The piece also had similarities to "Jackpot", a 1960 mbaqanga tune by Zacks Nkosi, who believed that "Mannenberg" was a rip-off of his piece. The various African genres that were incorporated into the song came from the Coloured and the Black communities of the country. Ibrahim stated that to the musicians the piece was an "affirmation ... that our inherent culture is valid."

Vally began to play "Mannenberg" from loudspeakers outside his store even before the album was released, and sold 5,000 copies of the recording in its first week on sale. The song became wildly popular, and the LP sold more copies in two years than any previous jazz LP recorded in the country, and it cemented Ibrahim's status as South Africa's most popular jazz musician. The piece itself has been described as the "most iconic of all South African jazz tunes", and its release has been identified as the moment at which the genre of Cape jazz became well-known, though it was not the first song in this genre. Vally did not have the financial ability to sell the album across the country, and so signed a deal with Gallo Records, the biggest South African record company at the time. Some 43,000 copies were sold in the first seven months; for comparison, an album selling 20,000 copies was considered a hit. The popularity of Coetzee and Jansen increased with that of "Mannenberg", and they became sought-after musicians in Cape Town nightclubs.

The song is reported to have inspired Nelson Mandela with hope during his imprisonment: Ibrahim recalled in a May 2012 interview for Voice of America's JazzBeat that the record was smuggled by a lawyer into Robben Island, where music was banned, and played in the control room over the loudspeakers, and that on hearing the song Mandela said: "Liberation is near."
