Abbas Hamis, better known as 20 Percent, is a legendary Tanzanian Bongo Flava artist and songwriter who holds a unique place in the history of East African music. He is most famous for his historic sweep at the 2011 Tanzania Music Awards (Kilimanjaro Music Awards), where he won a record-breaking five trophies in a single night—a feat that remained unmatched for years.

His stage name, “20 Percent,” reflects his humble philosophy that while he gives his all to his music, the remaining “80 percent” of a person’s success and life is in the hands of God and the community. After a long period of relative silence that led to various rumors, he has made a significant comeback to the music scene in late 2025 and 2026.
