They call it "space folk" and in a way, I quite agree with that. They hail from Poland and have been around for a few years now. Their music seems inspired by ancient folk music but drags in so much more, from ambient to psychedelic rock and from drones to post rock and even neo-folk. Of course, that brings in a lot of variation, but it also provides the album with a nice and mysterious atmosphere. The overall sound is calm, relaxed and quite immersive. Don't expect heavy guitars or screaming vocals. Instead, expect to become entranced by this musical gem. When I have to compare this music to other acts, I guess bands like Wardruna, Barn Owl and even Mike Oldfield come to mind. Perhaps I should mention that I really don't know that many acts in this region.
Anyway, that's not really important. What does matter is the fact that 'Liście na Księżycu' is an excellent album, containing five tracks of which three are enormous pieces of music that stretch out beyond the known musical horizons. I can't really pick out a favorite track as, once again, I simply prefer to play the album in its entirety and allow myself to float along with the mysterious soundscapes and vague melodies. I suggest you do the same.
