FYI - Ska if you don't know is a music style that has it's basis in Reggie and Jazz. It's know for it's fast up-beat tempo. Ska punk is just that fast, furious and fun, they usually have some kind of brass instrument in the band, commonly a trumpet.
I really like Ska punk, I'm a big fan on Less than Jake and Mad Caddies. I always think of summer, the beach and having a fun time when I listen to it.
One Korean band that I have heard talked about on some other websites and that I found on YouTube is called - Skasucks - I am guessing it's tongue-in-cheek as they seem to be one of the leading ska bands on the Korean scene. They have been around for over five years now, they do a lot of covers and apparently a really great high energy live show. I have not seen them live, but if I get the chance I think it would be a great one to go to.
