Double bass player Joris Vanvinckenroye is the band's main composer. His style is typically cinematic, melancholy and diverse. Some compositions are minimal in concept (e.g. 'Zilezi'); others bring an explosion of timbres and unusual times. In concert, Aranis creates an unforgettable atmosphere. Variation and expressivity hold the audience riveted. Chaotic structures and virtuoso crescendos alternate with serene intervals.
