In preparation for f(x)'s very first solo concert this January, they've released some awesome posters! The two posters are unique and completely f(x)'s style.

We're surprised that they haven't had a solo concert already, since they've been popular for years now. But better late than never! 'DIMENSION 4 – Docking Station' will take place from January 30 to 31 at Seoul Olympic Park's Olympic Hall.

f(x) will be performing all of their hit songs from over the years since 2009, so that should be a real treat for the lucky fans who will be able to attend.
