Aside from composers I know little music that has been made in Poland.
My favourite is Kult. Their song “Polska” is a classic that all migrants to Poland should know.
Another favourite of mine is “Baranek“.
I also like the prog-metal band Animations.
Otherwise, I like Masturbathor. I saw them live once in Sonisphere and were impressed by their performance.
Who do you like, then? Who would you recommend? Which singer do you believe to be the best singer in Polish history?
