Koben came into contact with music from a very early age onward through his father, a choir conductor. As a result, Koben received his first piano lessons from the age of five. However, he harboured a great curiosity and started playing many different instrumenst along the way, such as drums, guitar, bassguitar and the double bass. At the age of 14 he was accepted in the youth department of the Lemmens Institute for classical percussion, where he first came into contact with symphonic music. However, his curiosity remained at large and on his 18th he decided to study jazz double bass at the same institute, in addition to an MA in Western Literature at the Catholic University of Leuven. Ever since, Koben has performed a great deal of concerts with his double bass, both in jazz ensembles and symphonic orchestras. But his greatest passion was yet to reveal itself: composing. During his years of studying, he had already written several smaller pieces, but upon graduating, he decided to spend more time on composing. and soon after he received a first assignment, resulting in the composition Exsultate, dedicated to the eponymous choir, which premiered in December 2017. As a member of the new music ensemble Het Incident, he had the great opportunity to write a piece for their collaboration with the Ghent choir 2De Adem, conducted by Maarten Van Ingelgem. The composition Koben wrote for this occasion, titled Vreemd Fruit, is a modern rendition of the famous protest song Strange Fruit, and it premiered in may 2018 in the historical St. Baafs Abbey in Ghent. Furthermore, Koben received the assignment to write a composition for a mass memorial of The Great War. The work, written for extended choir and symphonic orchestra, is based on seven letters of army soldiers of various nations written on the battlefield and sent home to their loved ones, and is appropriately titled Letters from the Other Side. It premiered on the 11th of November 2018, 100 years to the day of the ceasefire.
