As to the subject matter, he goes on to say "there's a highly personal focus to it. Put it this way, I haven't heard any songs about farting or anything."
Yeah, that is sort of in the works. We don't have any kind of a timeline set up for it yet, but everybody is definitely wanting to do it, and everybody is writing for it, so I'm very sure it will happen, and we're all very stoked to do it. We've been having a good time writing songs, and so I'd say we've got well over half of it written but not recorded yet. So unfortunately we can't follow a very strict timeline, the way we would if we were a full time band, just because it doesn't fit in for us. We have to sort of work around the rest of our lives, but I would like to think something could happen as early as the middle of next year.
