It’s a tough day for bands with “Chi” in the beginning of their name, innit? The “Parks and Devastation” tour kicks off tomorrow  (4) in Pittsburgh, and when it does, Chiodos will have a completely different rhythm section on the road with them, as bassist Matt Goddard and drummer Derrick Frost have left the band. Here’s what the band had to say about their rhythm section and its replacements via Facebook:

We are excited and gearing up for the Parks and Devastation Tour that starts on Thursday, September 4th with A Day To Remember, Bring Me The Horizon, and Motionless In White. Before we hit the road we have some both exciting and unfortunate news. Derrick Frost and Matt Goddard have both chosen to discontinue touring and recording but instead spend more time with their loved ones and pursue other interests at home. It’s been a long and great journey with both of those gentleman, Matt dating back to the very beginning, and Derrick a part of 3 albums with us. We wish them the best in all that they choose to do moving forward. They’ve been long time brothers to us and always will be.

Our good friends Thomas Pridgen and Joe Troy are coming to rock with us. We have been rehearsing like crazy in Michigan so get ready for a great show. We’re very excited to have them join us on this journey as we’ve always been fans of their musicianship. We can’t wait for you all to experience this with us as we continue to tour and write new material. See you at city near you soon!

Thomas Pridgen is a pretty solid replacement. He’s played with The Mars Volta, and is also playing with Suicidal Tendencies and  Trash Talk, and is also in Giraffe Tongue Orchestra. It’s probably only a temporary thing, but it’s a pretty solid temporary side gig.
