On March 11, 2015, while the band was not touring, guitarist Mick Thomson was hospitalized after a drunken knife fight with his brother at Thomson's home in Iowa. The pair sustained serious, but non life-threatening, injuries. On August 2, 2015, during a concert in Hartford, Connecticut, the band was forced to stop performing after Venturella was suddenly rushed to hospital, after undergoing a medical emergency. After 20 minutes, singer Taylor told the audience the band would continue the concert, performing without Venturella. It was later discovered that Venturella had collapsed because of extreme dehydration.
