The group announced the news in a statement on Wednesday (23Sep15), revealing the rocker decided to leave the band to pursue personal interests.

Frontman Phil Labonte tells, "So after nearly 10 years Jeanne Sagan has decided to close the All That Remains chapter of her life. Everyone in All That Remains wishes nothing but happiness and success in any and all of her future endeavours."

Former Lamb of God and Devildriver bass player Aaron Patrick has been recruited to replace Sagan, and Labonte couldn't be happier with his new bandmate, adding, "We're sure he's going to be the perfect fit, and considering his musical history, I think he's going to add a new and cool dimension to All That Remains' sound moving forward."

Patrick will join the band on the upcoming HardDrive Live Fallout tour, which begins in Michigan on 14 October (15).

Meanwhile, Sagan has released a statement that reads: "It is with heavy heart that I depart from ALL THAT REMAINS. I've decided to follow my heart and pursue other opportunities in life. I truly appreciate the amazing experiences and the great fans over the last decade. I wish ALL THAT REMAINS all the best going forward."
