I was so excited at the thought of a new Thrice song or cover. Oh well. Glad to hear Manchester is releasing music again. Hopefully it's a sign they'll be recording soon.
They've been recording between tours for the past year. Andy played one of the songs he said would be on the fourth record acoustic at the RAGC show I attended in Baltimore back in July, and he said the aim was for the record to be out by the end of 2013, but hopefully around the same time Casey puts out the TDH record cause they want to tour their new stuff together. He's also posted pictures of him writing new lyrics on his instagram and tumblr.
