Broadcasting

As an NTA employee, Onwenu made an impact as a newsreader and reporter. In 1984, she wrote and presented the internationally acclaimed BBC/NTA documentary Nigeria: A Squandering of Riches which became the definitive film about corruption in Nigeria, as well as the intractable Niger Delta agitation for resource control and campaign against environmental degradation in the oil rich region of Nigeria.^[11] A former member of the NTA board, she has also worked as a TV presenter, hosting the shows Contact (1988) and Who's On? (1993) both on NTA Network.

Music

Originally a secular artist, Onwenu made the transition to gospel music in the 90s, and most of her songs are self-penned. She continues to write and sing about issues such as health (HIV/AIDS), peace and mutual coexistence, respect for women's rights, and the plight of children. She began her recording career in 1981 while still with the NTA, releasing the album For the Love of You, a pop album which featured an orchestral cover of Johnny Nash's "Hold Me Tight", produced by Berkley Jones. Her second album was Endless Life, produced by Sonny Okosun, and included another cover - the Everley Brothers' "Walk Right Back". Both records were released under the EMI label.^[12][13]

Onwenu's first album with Polygram, In The Morning Light, was released in 1984. Recorded in London, it featured the track "Masterplan" written by close friend Tyna Onwudiwe who had previously contributed to Onwenu's BBC documentary and subsequently sang back-up vocals on the album. In 1986, she released One Love which contained an updated version of the song "(In the) Morning Light from the previous album. Another song, "You and I", was re-recorded for the 2001 film Conspiracy starring Nkem Owoh and Onwenu herself.

For the 1988 album Dancing In The Sun, Onwenu adopted a more Afrocentric sound and collaborated with veteran jùjú artist Sunny Ade on the track "Madawolohun (Let Them Say)". This was the first of three songs the pair worked on together; the other two - "Choices" and "Wait For Me" - centred on family planning, and were endorsed by the Planned Parenthood Federation of Nigeria who used "Choices" in their PSA.^[14] Dancing In The Sun, Onwenu's final release on Polygram, was dedicated to Winnie Mandela, the subject of a song of the same name which Onwenu performed live when Nelson Mandela and his wife visited Nigeria in 1990 following his release from prison.^[15]

Onwenu diverted to Benson and Hedges Music in 1992 and released the self-titled Onyeka!, her only album with the label, after which she made the transition to Christian/gospel music. Her latest collection, "Inspiration for Change," focused on the need for an attitudinal change in Nigeria.

She is in partnership with Paris-based La Cave Musik, headed by a Nigerian cultural entrepreneur, Onyeka Nwelue and a UK-based Jungle Entertainment Ventures, headed by musicologist David Evans-Uhegbu. La Cave Musik is set to release her collection titled "Rebirth of a Legend". In recognition of her contribution to music and arts in Nigeria, she has been celebrated by professionals like Mahmood Ali-Balogun, Laolu Akins, Charles O'Tudor, and former PMAN president Tony Okoroji among others in the arts industry in Nigeria.^[16]

In 2013, Onwenu served as one of the three judges on X Factor Nigeria.^[17]

Acting

Onwenu's first movie role was as Joke, a childless woman who adopts an abandoned baby in Zik Zulu Okafor's Nightmare.^[18] She has since featured in numerous Nollywood movies, and in 2006 she won the Africa Movie Academy Award for Best Actress in a Supporting Role for her performance in the movie "Widow's Cot". She was also nominated that same year for Africa Movie Academy Award for "Best Actress in a Leading Role" in the movie "Rising Moon".^[19] In 2014 she was in the movie Half of a Yellow Sun with Chiwetel Ejiofor and Thandiwe Newton, and Lion Heart (2018).
