Ewa Demarczyk
Apparently she's a famous Polish musician who would sing poems in an interpretive and usually emotional manner... in a foreign language (I only speak English). She would then have someone else compose chamber-like music to go along with her vocals... I'll admit that I don't know too much about her other than I really enjoy her music. I recently listened to
Ewa Demarczyk śpiewa piosenki Zygmunta Koniecznego (1967), and I love every second of it... which is surprising because I typically don't listen to this sort of music.
Here are a few videos:
