Drummer Alex Bent has parted ways with Trivium after nine years. The news comes just hours before the band is due to perform at Aftershock Festival in California. No cancellation has been announced, so it is assumed the gig will go ahead with a stand-in drummer. Bent's abrupt departure was announced via a post on his Instagram page, with no reason given for the split. In his statement, Bent wrote: "I am beyond grateful for the incredible past 9 years with Trivium - filled with unforgettable moments, music, and friendships that I'll always carry with me. I'm so proud of every record and tour we created together, and I know Trivium will continue to dominate the world. "They'll always have my support. While this chapter has come to a close, this is by no means the end of my path as a musician. I'm excited for this new chapter, and I look forward to continuing to create, perform and share music in new ways. "Thank you to everyone who has supported me along the way. Your encouragement means the world." Trivium frontman Matt Heafy replied to the post, saying: "Wishing you and your family nothing but the best." This had fans speculating Bent had left for family reasons, but the drummer replied to one comment with: "My family is all good, man." Trivium are due to launch their 32-date Struck Dead Tour on 31 October. There is no news on who might be on drums.
