I always thought I already loved them before I went to my first concert, but I had to change my mind: I fell in love with them again, and even harder than I could ever imagine. They are a million times better on stage than on the CDs, in my opinion, if that is even possible.
Is it a "full" GD concert you’re going to? Because if it’s a festival, it may not be that overwhelming, which has nothing to do with the band itself, but with the audience. I experienced that the audience at festivals sometimes sucks when GD is headliner, because many of the people (which I of course don’t understand) don’t come because of GD, some even hate them (yeah, suckers). But if it’s a full GD concert, the whole audience becomes one big community, and they all sing along, and it’s just awesome.
Unfortunately, I only get to see them at a festival in Germany this year, there are no full GD shows in my country (yet, I hope!!). But a festival is still better than nothing, of course
