Cill (born Chioma Ogbonna) is a Singer/Songwriter, guitarist based in Lagos State, Nigeria. Born and raised in Edo State, Nigeria to a family of seven, she was drawn to music at an early age. Her interest in music was fueled by her eldest brother who constantly introduced anyone who cared to new music in various genres and her father who would wake up each morning to tunes from Jimmy Reeves, Christy Lane, Don Williams, Majek Fashek, Evi Edna, Sunny Okosun, etc. She became interested in the guitar at an early age and used her first salary as a teacher to purchase her first guitar. The ultimate proof of her love for music was when she left her job at KPMG in 2016 to pursue a career in music.
Cill loves telling stories using music and uses her music to promote social causes. She is a member of the Music for Democracy Network collaborating with other artists from different parts of the world to promote issues of democracy using music. In 2019 she received the Accountability Music Award by Accountability Lab and One Campaign, being nominated alongside great artists such as Falz, Fatoumata Diawara, Sauti Sol and Platinum Prince.
