I'm a fan (and you should be too) because...
Three Days Grace is just the definition to the word "awesome"
I'm from denmark and so i haven't really been able to go to any live concerts, even though i tried.
It always seems to be sold out, which is obviously another proof that the band rocks.
The reason for my being a fan is, that the music makes sense, compared to other bands in the same style.
The music, and especially the song "Never Too Late" (my personal favorite) helped me get through a tough time, and learned me, that even though life spits on you and this day might be black and cold, you will get through if you just hold your head high, and i did.
Thank you Three Days Grace, and please, keep on rocking!
