Haase & Rößler: Artifizielle Präsenz (Trailer)


November 2017: Dos Trazos, the second album of Haase+Santis !

Dos Trazos, the second album of Haase + Santis is out now!


"A disc where temporality and form are given through the organic needs of the moment, which takes us

into subtle states of listening, where we can manage to enter the fine interwoven fabric and the

decisions through which the music was tacken on, at the personal level, a work of brief landscaping

with an occultist essence, two strokes that propose contrasting states from the same nature,

listening and freedom.”


recorded in Estudio Errante, 2017
