Paramore bassist and founding member Jeremy Davis (pictured above on the left) has left the band. Frontwoman Hayley Williams and guitarist Taylor York broke the news in a Facebook post, describing the split as “really painful”:

These last few years have held some of the most fulfilling moments we’ve had yet... as people, as friends, and as a band. The Self-Titled era was one that we knew would be important for us but also one we'd eventually have to move on from. In moving forward, there is growth, pain, and change... and sometimes the change is not at all what you hoped for. We’ve written and re-written this countless times and there’s just not a good way to put it... Jeremy is no longer going to be in the band with us. To be honest, this has been really painful. After taking time to consider how to move forward, we ultimately found that we really do believe Paramore can and should continue on. And so we will.

We’re really thankful for the people who have helped see us through hard times before and what we’ve discovered is that those people are just as much a part of this as we will ever be. We’re hopeful for Paramore’s future and we’re also excited for what Jeremy’s going to do next. Thank you all for your support and your belief in us. It’s kept us going. We will see some of you really soon on Parahoy. If you’re not coming on the cruise, we will still see you in 2016.

Davis helped found Paramore alongside Williams and brothers Josh and Zac Farro in 2004. He’s appeared on all four of the band’s albums between their 2005 debut All We Know Is Falling and their 2013 self-titled effort. The Farro brothers left Paramore in 2010.

Williams and York promised to continue on as Paramore without Davis. They’ll play their first shows with their revamped lineup this spring when they embark on the Parahoy cruise from March 5-9. There will be guest appearances by Chvrches, X Ambassadors, New Found Glory and more.
