“I’m very grateful for everything playing with DKM has brought me and I’m sad to be going but I feel like the time has come for me to try working on different styles of music and some of my own projects, I’m ready to spread my wings as they say,” Orrell said in a message on the band’s web site.

“It goes without saying that we’re very sad to see Marc go but we’ll always be great friends and he will be part of the Dropkick Murphys family forever,” his band mates said.

DKM is adding Boston musician Jeff DaRosa to its lineup and the band’s concert schedule is not affected by Orrell’s departure.

“We want everyone to know that we are still very committed to Dropkick Murphys and making our fans happy. As you all already know Tim is an extremely accomplished guitar player and musician so the transition is going to be very smooth,” the band said.
