If you are planning on going to see Shinedown and Three Days Grace, on their upcoming co-headling tour in a couple of weeks, you may want to hold off on buying your tickets, at least if you're a Three Days Grace fan.

Yesterday, Three Days Grace shocked their fans by announcing Adam Gontier's departure. They are claiming he left due to 'health reasons' but I'm not buying it. They are replacing Gontier with My Darkest Days' Matt Walst.

Now if you are wondering what the new TDG will sound like, never fear. The band has already re-recorded some of their tunes with the new guy (which can't be a good sign for Adam's future with the band).

So, if you like Three Days Grace and their new 'cat getting raped' sound, you can buy your tickets here.
