Yes, sadly, the rumors are true...Adam is leaving Three Days Grace.
Below is the OFFICIAL release from the band.
We appreciate everyone’s concern about Three Days Grace. We found out on December 21st that Adam wished to resign from the band. In a letter to us Adam indicated that he was resigning from the band due to a non life threatening health issue and wanted the band to continue moving forward without him. We were as shocked as many of you were to hear the news. Three Days Grace has always been and will continue to be not only our job but our passion. Instead of cancelling the tour, we felt an obligation to you, the fans, to forge ahead and put on the best show we can. Brad recently reached out to his brother Matt Walst, lead singer for My Darkest Days to fill in for the tour dates already announced. We've been hanging out and rehearsing with Matt and look forward to rocking the stage in a few weeks! As of right now, Matt's role is temporary and as far as the future and beyond this tour, we are taking it one day at a time. - 3DG
That's Matt Walst rocking the stage with My Darkest Days. I've watched him perform live when his band was touring with HINDER. I think he has enough energy and stage presence to fill Adam's shoes for the remainder of 3DG's scheduled tour. Like any devoted Adam Gontier fan, though, he's not gonna be the same! But as a Three Days Grace fan, I can only hope for the best!!! Keep on rocking, guys!!!
