The Missouri State Fair is quickly approaching, and we're hooking our listeners up with some of the hottest concert tickets of the summer. One highly anticipated show among the rock community in Mid-Missouri is the Three Days Grace concert with Hinder. However, fairgoers may be surprised to hear that original Three Days Grace frontman Adam Gontier and Hinder's lead singer Austin Winkler won't be performing at the show on August 17. Why not?

Adam Gontier resigned from Three Days Grace back in January of this year, just weeks prior to their upcoming co-headlining tour with Shinedown. Adam told the band that he was resigning due to a non life threatening health issue and wanted the band to continue moving forward without him. Singing duties have taken over by My Darkest Days frontman Matt Walst, who will perform at the Missouri State Fair.

Here's a video featuring a recording of Three Days Grace's hit "Riot" with replacement singer Matt Walst on vocals. Click here to hear the original song.

 

As for Hinder, lead singer Austin Winkler has returned to rehab for the second time, leaving Hinder to perform their shows without him through Aug. 26, including the show at the Missouri State Fair on Aug. 17. Discussions with 'America Idol’ season seven winner David Cook to perform with the band, but he declined. Hinder was able to get Saving Abel frontman Jared Weeks will fill in for Winkler on their tour.

The concert is sure to be a rockin' one, and all other original band members are expected to perform. Will you still go to the concert with replacement singers filling in?
