Apala, a traditional style from Ogun state, one of yoruba state in Nigeria, became very popular in the 1960s, led by performers like Haruna Ishola, Sefiu Ayan, Kasumu Adio, and Ayinla Omowura. Ishola, who was one of Nigeria's most consistent hit makers between 1955 and his death in 1983, recorded apala songs, which alternated between slow and emotional, and swift and energetic. His lyrics were a mixture of improvised praise and passages from the Quran, as well as traditional proverbs. His work became a formative influence on the developing fuji style.
