Ray Paczkowski, keyboardist of the Trey Anastasio Band and duo Soule Monde, was recently diagnosed with a brain tumor and underwent a successful surgery over the weekend, Anastasio announced via social media earlier today.

“After a few months of experiencing headaches and nausea, Ray ended up in the emergency room not long ago,” Anastasio writes, noting that his friend and bandmate is “expected to make a full recovery” and that Paczkowski “was in good spirits, despite the situation.”

Anastasio, Paczkowski and TAB are set to open their spring tour dates April 17 in Cleveland, OH.
