Ti Harold's love for music in all its forms and expressions has given him an atypical career that straddles the evangelical sector and the secular music world. He is comfortable in several registers and has embarked on an interesting journey between musical genres.

Growing up, Harold St. Louis showed an early interest in drums and singing, but he also learned to play the keyboard and initiated himself to the piano and bass. Recently, on Sunday, April 23, 2023, he was playing the keyboard and singing at the ceremony celebrating the life of composer Daniel Larivière. Nevertheless, he tells us that the drums remain his favorite instrument to this day.
