Experience '26
“A Mighty Long Way”
About the Concert
Right after school, the Lord instructed him through the inspiration of Isaiah 2. He has a mandate to restore the Tabernacle of David, signifying the true essence of praise and worship, with his music as the medium. In all of these, Christ is the focus.
In preparation, after receiving this commission, he put together a team of young and vibrant ladies and gentlemen who would join as fellow laborers in carrying on the mandate. Upon deeper fellowship with the Lord, he was inspired by John 7:37–38. Though he had not seen Him, he believed on Him for the promise of the Holy Spirit. Based on this, the name RIVERFLOW was birthed.
It was seen as more than a team — it was a movement. They met, prayed, shared God's word, brought up ideas, and witnessed to people about Christ through outreaches and donations. It has been the Spirit leading him in all things.
This inspiration led Onasis Kontor to gather people from all walks of life in one place to lift up their hearts in worship through music. This is how the Riverflow Experience came about. It has been a gathering of people from all walks of life to project a sound of worship and sing songs of glory, deliverance, and salvation. For eleven years, the Lord has led us from one point to another.
This year marks a milestone in our journey, reminding us of where we started and how far we have come. Hence, “A Mighty Long Way.”

Onasis discovered his calling early. At just seven years old, he was leading praise and worship in church, and by twelve, he was ministering solo at major church conventions, captivating listeners with his distinctive vocal expression.
During his time at Kumasi Academy, he became a key figure in the school's contemporary choir as a lead singer and music director, even while writing, recording, and featuring on gospel projects — including “Obeygye Wo” and “God of Increase” (featuring Milliel) in 2009, followed by a Hymnal Medley in 2010.
While at Zenith University College, he balanced academics and ministry, releasing multiple singles between 2011 and 2014 — notably his personal favorite, “Sweet Song.” In 2019, he recorded his first full-length album, The Set Time — a 13-track project released in September 2020 that continues to inspire audiences.
His ministry has reached international platforms such as GAPNET's Many Hours of Non-stop Praise and Worship, organized by Logos Rhema Foundation, where he has shared stages with gospel ministers from around the globe.
Currently serving as Music Director at the headquarters of Top Ministries International in Sunyani, Onasis goes beyond performance — organizing charity concerts, gospel workshops, and choir training sessions to equip the next generation of worship leaders. Known as one of Ghana's most sought-after gospel ministers, he credits his dedicated team, RF, for their invaluable support in fulfilling his mission.
Married to Elizabeth Antwi and blessed with three daughters, Onasis Effah Kontor continues to carry a sound that transforms lives and nations.
“I believe my works will speak for generations to come — and I will stop at nothing until God's purpose is fulfilled.”
