harmonies during the very early 1960s when groups including The Skylarks and the Manhattan Brothers began copying American vocal bands, mostly doo wop. Rather than African-American four-part harmonies, however, South African bands used five parts. The Dark City Sisters were the most popular vocal group in the early 1960s, known for their sweet style. Aaron Jack Lerole of Black Mambazo added groaning male vocals to the female harmonies, later being replaced by Simon 'Mahlathini' Nkabinde, who has become perhaps the most influential and well-known South African "groaner" of the twentieth century. Marks Mankwane and Joseph Makwela's mbaqanga innovations evolved into the more danceable mgqashiyo sound when the two joined forces with Mahlathini and the new female group Mahotella Queens, in Mankwane's backing group Makhona Tsohle Band (also featuring Makwela along with saxophonist-turned-producer West Nkosi, rhythm guitarist Vivian Ngubane, and drummer Lucky Monama). The Mahlathini and the Mahotella Queens/Makhona Tsohle outfit recorded as a studio unit for Gallo Record Company, to great national success, pioneering mgqashiyo music all over the country to equal success. In 1967 Miriam Makeba released US hit "Pata Pata". 1967, Izintombi Zesi Manje Manje, an mgqashiyo female group that provided intense competition for Mahotella Queens. Both groups were massive competitors in the jive field, though the Queens usually came out on top. Soul and jazz The late 1960s saw the rise of soul music from the United States. Wilson Pickett and Percy Sledge were among singers who were especially popular and inspired South African performers to enter the field with an organ, a bass-and-drum rhythm section and an electric guitar. In the 1960s jazz split into two fields. Dance bands like the Elite Swingsters were popular, while avant-garde jazz inspired by the work of John Coltrane, Thelonious Monk and Sonny Rollins was also common. The latter field of musicians included prominent activists and thinkers, including Hugh Masekela, Abdullah Ibrahim (formerly known as 'Dollar Brand'), Kippie Moeketsi, Sathima Bea Benjamin, Chris McGregor, Johnny Dyani and Jonas Gwangwa. In 1959, American pianist John Mehegan organised a recording session using many of the most prominent South African jazz musicians, resulting in the first two African jazz LPs. The following year saw the Cold Castle National Jazz Festival, which brought additional attention to South African jazz. Cold Castle became an annual event for a few years, and brought out more musicians, especially Dudu Pukwana, Gideon Nxumalo and Chris McGregor. The 1963
