Approaching Complexity is the fourth album from Netherlands based ambient-beats duo Tangent. This follow-up to 2016s Collapsing Horizons finds the duo expanding their sound by adding reoccurring expressive piano themes to their composite of skyward ambience and unfolding beat formations. The album is said by the duo of Ralph van Reijendam and Robbert Kok to be about the transition from basic forms to complex structures which are often seen in nature during the transitioning of seasons. They add that Life awakens from hibernation and evolves from being introverted to becoming extroverted, even building upon the remnants of previous cycles and evolving into new realms. Approaching Complexity for Tangent is all about their evolution as progression has been a clearly defined constant in their output as a whole. Each work effortlessly transitioning unto its predecessor.
