Mark O’Connell has officially announced his departure from Taking Back Sunday.

After nearly 25 years as the drummer of Taking Back Sunday, I want to confirm that I am no longer with the band. It’s taken me some time to address this. Thank you for your patience as I’ve reflected on how to share my story. First, I want to thank the fans – your love and support have meant everything to me. You’ve been the heartbeat of TBS, and a huge part of my life for nearly a quarter of a century. I owe it all to you. My departure wasn’t an easy decision, and it wasn’t entirely my own. Over the past few years, I’ve focused on my family and personal growth, including committing to my sobriety. Unfortunately, during this time, I didn’t always feel the support I needed from those I thought of as brothers, and creative differences made it hard to move forward together. Speaking of, I’m excited to share that I’ll be releasing new music soon – both as a solo artist and with some old friends. [

Eddie Reyes, formerly of Taking Back Sunday, recently mentioned on a podcast that Mark had was no longer in the band:

”I just recently started speaking with Mark again, who’s apparently, uh, he walked away from, er, he’s not in the band anymore.”

Mark has confirmed this on Instagram.

Taking Back Sunday crashed a wedding between fans over the weekend. They shared some videos on Instagram.
