Lagbaja (born Bisade Ologunde in Lagos) is a Nigerian Afrobeat musician.

According to Lagbaja, his mask is used as an icon of man’s facelessness. Lagbaja is a Yoruba word that means "nobody in particular". It depicts the anonymity of the so-called “common man”. The mask and the name symbolize the faceless, the voiceless in the society, particularly in Africa. He is also known as "Omo baba mu'ko mu'ko"

Though the concept was developed long before that, his first album (entitled Lagbaja) was released to national acclaim in 1993. Over the years and more albums later, the music continues to fascinate with its unique focus on a core of African drums. His music is a product of various influences ranging from traditional Yoruba music to Jazz. Often the music is purely instrumental- an interplay between traditional Yoruba percussions, drums, chants, and western instruments, especially the saxophone. When there are lyrics, they are primarily sung in Yoruba, English or a blend of the two as is colloquially spoken in Yoruba cities. Many of his songs dwell on serious social issues, while others simply entertain. Some are dance inducing while others pass serious messages in humorous ways.

P-Square are a Nigerian R&B duo composed of identical twin brothers Peter and Paul Okoye.

The story of P-Square began in St. Murumba secondary school, a small Catholic school in Jos, Nigeria. Identical twins Peter and Paul joined their school music and drama club where they began singing, dancing, and miming songs by MC Hammer, Bobby Brown and Michael Jackson.

They later formed an a cappella quartet called "MMMPP" (M Clef a.k.a. Itemoh, Michael, Melvin, Peter and Paul). Drawing inspiration from their music idol Michael Jackson, they began break dancing, formed the group called "Smooth Criminals" in 1997. They droped M Clef from the group "MMMPP" which later was changed to "MMPP". Their artistic talent and precise dance routine soon made them household names in the city of Jos, where they performed at school functions and other occasions.

Later in 1999, Peter and Paul returned to music school to develop their skills on keyboard, drums, bass and rhythm guitar. Their work includes the soundtracks for a number of films like Tobi, Mama Sunday, Moment of Bitterness and Evas River.
