Born in 1983 in a small town in the southern parts of the Netherlands, Clemens started playing the keyboard at the age of 7. He took keyboard lessons and music theory lessons at Kunstschool Meander for eight years, during which he accompanied the local youth choirs on keyboard and piano at rehearsals and many live performances. In secondary school, he became more interested in symphonic and metal music, and started to combine those two elements in a band.

In 2002, he took lessons for one year at the Brabants Conservatorium while he continued composing music and refining his skills. In 2003, he formed the melodic metal band Vaultage which released one well-received EP. Vaultage was disbanded two years later, making room for a new band: Carach Angren.

A great deal of the music in Carach Angren is composed by Clemens, using classical music as a foundation and inspiration.
After two official CD releases and more than 100 international shows, Carach Angren’s achievements continue to be praised by the international press and the increasing number of fans of their music.

Eventually Clemens decided he wanted to extend his work as a composer to other media, such as film. He has already composed scores for several short films and other projects and is eager to further expand his experience in these fields.
