this time tiefenrausch welcomes a new artist in their dub techno family. förster joins the label with his aqua viridis ep and presents a debut with three tracks. as part of his „grün“ series, every track stands for a different vibe of the genre. the a-side comes with a pumping, reduced smasher, that definetely aims on the dancefloor. side b brings more immersed deepnes. „grün xv“ and „grün xviii“ evoke an abyss and enwind the listener with dublime deepness. all covered up by the artwork of alex ketzer and the imagery from jules vernes „20.000 leagues under the sea“.
