Three Days Grace frontman Adam Gontier has left the building! The band has replaced Gontier with singer Matt Walst from My Darkest Days, who is also the brother of 3DG bassist, Brad. He will be on board for at least their latest tour with Shinedown, if not longer.
According to the band's site, Adam left "effective immediately" citing a health issue. Brad Walst, stated in a press release, “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.”
