Belgian pianist Harrison Steingueldoir first encountered a piano at the age of seven. He got his music education in MAAK and the Royal Conservatory of Antwerp where he discovered his love for exploring and creating. This led into playing jazz and improvised music, but also composing and arranging for small and bigger ensembles (like the Brussels Jazz Orchestra).

In 2015 he formed Donder , a group with Casper Van De Velde and Stan Callewaert.
In 2020 he joined the Nir Shemmer band (americana/folk music)
In 2022 Erik Bogaerts and Harrison formed a duo project.

Throughout the years several prizes and projects gave him the opportunity to perform in Belgium, Luxembourg, France, The Netherlands, Germany, Italy, Norway, Denmark, Portugal and Japan.
