Not a lot of details yet, but Cave In has posted a little something about their collaboration with Converge. The two bands are on tour together and you can check out the dates we posted earlier. Here's the blurb from Cave In:

To cap off our summer, we've spent some time out in Salem, MA at Kurt Ballou's God City studio working on a collaborative recording project between us and the Converge fellows. It's been a much-talked about thing between both camps, and with the exception of one jam session a couple years ago, there hasn't been any action made until now. We don't want to completely spoil the surprise, but we can tell you that so far we have five tunes in the making and they all came together pretty quickly. And they are "tunes" in their own right, as opposed to meandering jams or total self-indulgent wanking. The guys in Piebald joked that it's sort of like the Merrimack Valley's own Temple Of The Dog, and we'll just end it at that. No word on when the project will be completed or who's going to release this thing - but we'll keep you posted.
