Some music

Hey, I'd like you to listen to this band and lmk what you think about them.
A year ago they presented their music in my school at the end of the year (we have such evening with students showing what they can do apart from learning at school :)) and since then I'm watching how they become more and more popular.
I like them very much, but I'd like to know your feeling about them.

The band is called "Undergrunt" and it's from Warsaw, Poland.
