Kang John Jock, professionally known by his stage name as Kang JJ, is a sensational South Sudanese Afro Pop singer, songwriter, poet and a freedom activist.

Kang JJ, Born in 1980, was named as Kang at birth. Kang in the South Sudanese Nuer language means a sound of a trumpet or simply musical. Kang inherited the gift of singing from his father who performs outstandingly at local weddings, incarnations ceremonies, and later on in church in their hometown in South Sudan. By 2012 Kang JJ won the best Afro beat entertainer of the year in South Sudan. His song “Free at last”, which was released in July 2011, is still one of the most popular songs played on national broadcasting stations, radio stations and also on social media. "Free at Last" is recognized by many South Sudanese as one of the best independence song in South Sudan. His hit song, “candidate”, was also recognized as one of the best election song in 2010. In addition to musical talents, Kang JJ is a poetic sapient who expresses himself through poetry on burning social & political issues affecting the livelihood of the common people.

In Addis Ababa, Ethiopia, Kang was introduced to this Ethiopian well wisher, Fitsum Tadesse, by a friend. Upon listening to King JJ’s Capella of the song that he had composed, Mr. Fitsum was captivated by his vocals and said “you are not sitting in the house with that talent”. He told him to go to a recording studio and paid for Kang JJ’s ever first record, ‘Muc ti nguan’ (plentiful gifts - a song that describes how rich the black African in South Sudan could have been with all the blessings/natural resources, if it wasn’t for war and marginalization) and released it in 2004, just a year before the Comprehensive peace Agreement(CPA) that led to a referendum and paved way to South Sudan independence in 2011, signed in Nairobi, Kenya. In 2006 he performed "Muc ti Nguan" during the CPA anniversary in Addis Ababa where he patriotically left the crowd in tears of relieve in an atmosphere of a ceasefire and a hope for an end to the war in Sudan, the Africa’s longest Civil War.

His other single album “Wengdial a puonyde”(all eye on her), released in 2005, got him the sponsorship of ‘Sudan Radio Service’ (now ‘Eye Radio’) in Nairobi Kenya for a full album record in 2007. Kang JJ had started an Inner peace tour in November 2018 in East Africa and his current destination is Australia.
