International popular genres like Western dance music, rock or pop music and African-American music have had a profound effect on modern Sudanese music. As in other African countries, one of these influences were the military brass bands. Playing in such bands attracted many young military recruits, who later carried their newly learned music style and instruments over to popular music. The result was a kind of dance music, referred to as (Sudanese) jazz, which was not related to the American style of jazz, but similar to other modern dance music styles throughout East Africa. Prominent band leaders in this era include Abdel Gadir Salim and Abdel Aziz El Mubarak, both of whom have achieved international fame and distribution of their albums. – In retrospect, the 1960s up to the 80s were called 'The Golden Age of Sudanese popular music'. This period was documented by re-issued albums in 2018, when researchers from the US and Germany were looking for still existing recordings from that era. Out of this research, several digitised albums of popular music from Sudan, including stars like Abdel Aziz El Mubarak, Kamal Tarbas, Khojali Osman, Abu Obeida Hassan, Kamal Keila, Sharhabil Ahmed, Hanan Bulu Bulu, Samira Dunia and, most famously, Mohammed Wardi were digitally remastered and are available on the international market.
