Three Days Grace definitely shocked fans Wednesday (Jan. 9) with the news that they were replacing frontman Adam Gontier with My Darkest Days' Matt Walst after Gontier resigned from the band due to a "non life threatening health issue."

In his own letter to fans, Gontier stated, "After twenty years of being part of an ever evolving band, I have been inspired by life, to move on and to continue to evolve on my own terms," suggesting that his decision was more about starting a new chapter than a health concern.

Gontier has been not only the voice of the band, but arguably the group's most recognizable face, as well. Given that the group had already committed to a co-headlining run with Shinedown this spring, it's understandable that they would want to honor that commitment, but the question remains of whether or not it was the right decision. Our Readers Poll today asks whether or not you think Three Days Grace should continue without Gontier still part of the band.

There are several schools of thought on this. One is that the band members have every right to want to continue to play their music and given Gontier's sudden departure, to stop now would not offer themselves or the fans any sense of closure. Plus, at present, the group has only listed Walst's participation as "temporary," meaning a decision on whether or not to continue beyond their current tour is not a definite and these dates could either be their farewell or a springboard to a fresh start.

However, It could also be argued that Gontier's voice is indelibly tied to the band and by playing (or even potentially recording) without him, they risk altering how fans view their legacy.

Then there's the idea that maybe it's too early to render a judgment as to whether this was the right decision to continue playing or not until Walst is given a chance to play for audiences and fans can have some time to sit with it.
