He made the announcement on his blog:
I wrote all these songs over the course of the last few years since Buttsweat and Tears came out. They came together really slowly and for a long time, I didn't know what to do with them because while some were pretty punk rock and could conceivably been Falcon or TLA songs, most of them were not. it's a weird kind of collective, but it's really just four of us at the core of it, although nobody but me is on every song. Most of it is me and Nick playing and Eric and Shawn producing.
He notes the The Lawrence Arms have definitely not broken up which is probably evidenced by their upcoming tour. Alternative Press notes that a full length is due for release in February and it will be preceded by a three-song digital EP. The EP is titled A Man With The Passion Of Tennessee Williams and is due out December 27, 2011.
