Adam Gontier Of Three Days Grace Leaves The Band

Earlier today Three Days Grace announced that lead singer Adam Gontier has left the band due to a health issue. No further explanation was given and it looks like the band was caught off guard by this announcement too; bassist Brad Walst said:

We were surprised and distressed by Adam's sudden departure.  We are however very excited for this upcoming tour, and to have my brother Matt stepping in as lead singer.

As mentioned above, Matt Walst -lead singer of My Darkest Days- will be filling in during this upcoming tour.

If you've got tickets to their upcoming shows, here's a taste of The High Road, Chalk Outline, and Riot performed with Matt Walst at the helm.

We wish Adam a speedy recovery.

Update 5:15pm Jan 9, 2013: Three Days Grace have released an official statement:

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
