Adam Gontier

The recent exit of Three Days Grace singer Adam Gontier from the group shocked many in the music industry, but probably no one more than the rest of his bandmates. After offering a very brief statement on Gontier's exit and revealing that My Darkest Days frontman Matt Walst would be filling in on their upcoming tour with Shinedown, more and more details have begun to leak out.

While singer Adam Gontier shocked his fans by announcing his departure from Three Days Grace yesterday (Jan. 9), he's not retiring from the stage entirely. The vocalist will play his first show since leaving the band next Thursday (Jan. 17) as part of the special acoustic 'Rock for Recovery' benefit for victims of Hurricane Sandy at New York's Gramercy Theatre.

As Three Days Grace fans continue to absorb the surprising news from earlier today (Jan. 9) that frontman Adam Gontier has left the band, the singer himself has released a heartfelt letter explaining his departure.
