Roser/Asselbergs is a Haarlem based jazz duo formed by the Swiss pianist Daniel Roser and the Dutch drummer Gustan Asselbergs. The music of Roser/Asselbergs is rooted in improvisation. The seemingly infinite musical possibilities of the drums-piano duo is an important drive for discovering new perspectives on rhythm and sound and thereby creating microcosmoi, dynamic soundscapes and textures of improvised material. Roser/Asselbergs stands for a spacious type of music that is concerned with the richness of instantly composed rhythms and harmonies in a collective flow. Each note is a gesture inviting the listener to embark on a journey.
