Chasse had this to say:
Rise Against was the best three years of my life. I've met so many amazing people and been all over the world with the best friends anyone could ask for. I'll never stop writing or playing music. Thank you to everyone over the past few years for all of the love and support.
The band explained that Chasse's departure had to do with their extensive touring schedule. To that end, the band has enlisted guitarist Zach Blair, of Only Crime.
