Straight from the Goldfinger mailing list:
"After 7 years in Goldfinger, Charlie has decided to move on and is no longer in the band. Although we are saddened by the news, we know that you, our fans, would expect us to carry on with the recording of our new record and play the shows we had scheduled for this fall/winter with Reel Big Fish. Finding a replacement won't be easy or done with haste. So, in the meantime, our friend Brian Arthur from Unloco will join us on guitar. We hope you will join us in wishing Charlie the best with his future endeavors. Thank you for your continued support and we will see you soon!
John, Darrin, and Kelly"
