A private argument between the pair became public at a show in Tennessee, with drummer Spencer walking off stage, followed by his bandmates, leaving singer Moody on his own.

Moody later blamed the incident on technical issues, while Spencer said he wasn't proud of what happened that night. But guitarist Zoltan Bathory said the spat had to happen to avoid a bigger issue further down the line.

Kael tells Metal Wani: "Despite what may have been going on that day, we never want to put that out in front of the fans. Those dudes and girls paid a lot of money to come out and see a show, so that was one very embarrassing day for us.
