His late father, Chief Obinaetiti Onye Agulueri, was a distinguished composer, lyricist, and musician before his passing. Initially, Olisado had no intention of pursuing a career in music. He journeyed abroad with his team members, but during his travels, he claimed to have encountered a spirit that instructed him to return to Nigeria and embark on his musical path.

Olisado's musical journey began at the age of 8 when he started singing at Odoziobodo Catholic Church in Onitsha, Anambra State.

Today, Olisado is among Nigeria's most prominent highlife artists. He currently commands a minimum performance fee of one million naira for live shows. Throughout his career, he has collaborated with notable artists such as Onyenze Nwanobi Na Ogidi and Ayaka Ozubulu and so many others.

In 2021, Olisado paid homage to Okoli Onuabuchi Jonathan, also known as Nkwachukwu, by releasing a special tribute track in his honor titled "Onu Mmadu Aburo Onu Chukwu."
