inspired by your marzanna playlist post I went on a search spree and found a band called Furia. they have an album titled "Marzannie, Królowej Polski", which is an amazing title and feeds right into the confusing mess of Matka Boska-is-secretly-Marzanna uh, thing I have going on. but unfortunately their music is not in the least what I'd associate with her ;__; unless you go for a strong "winter is pain and suffering" angle.
imagine when I found them - the excitement! and then I gave them a listen and, well, not particularly my thing and not really what I associate with her, so yes, same :<
