Welcome visitor!

My name is Harold Groenenboom and I am a pianist, composer, programmer and sound artist from the city of Rotterdam.

For me music is one of the most powerful ways for people to express themselves. I express myself through my music, and computers allow me to tell my stories. My aim is to make computer music as expressive as it can be and I'd love to take you with me on my journey.

On this website you will find a selection of my work, including music, sonic art, programmed software, generated visual art and other media.
