Asva-presences of absences
Asva is an interesting collective led by Stuart Dahlquist (Goatsnake,ex Byurning witch, Sunno))) ) what they play is mostly long drone songs, but with the addition of other elements. Their last record Presences of absences, released in 2011, see Asva evolve toward less guitars and heaviness and more organ layers and melodic singing, giving the record a strong progresive and "spiritual" vibe. maybe drone purist would dissaprove (but maybe Asva was already too original for them) but the result is a sucess in my opinion, the record having a strong personnality and being really enjoyable at the same time.
but just try it and make your own opinion!
