For fans of:
Sigur Ros, something very dreamy and atmospheric (I don't know any bands that match this sound) and Tomydeepestego.

CHARUN plays a dreamy, atmospheric post-rock/metal instrumental band from Italy. There's quite a bit of atmospherics going on here, especially in the opening track "De Brevitate Vitae" which is drenched in water/liquid effects. Listen to this if you want to relaaaaaaaaax.
