Big Bang, Shinhwa, or Epik High?

Travel Info
Choose one of the three if you can. Otherwise, recommend a group that's somewhat current in Korea.

If I had to choose from what you put above... I would choose Epik High!!

Others
There are too many bands to name, but from your list, I LOVE Big Bang. Listen to 'We Belong Together'
Drunken Tiger, all the way! They're more hardcore rap and not quite as "mainstream" as the groups you mentioned, but I gotta recommend them.

SHINHWA =)
Shinhwa would give you the best idea about what is most popular now in Korea, but if you grew up with American music, it seems kind of cheesy.
Epik High
