While we don't know any exact details about the new album from Weezer, they've been slowly but surely dropping hints and videos from the recording process. We saw them perform a new song 'Back to the Shack' on their Weezer cruise a little over a month ago, we heard a 20 second teaser a couple of weeks ago, and now they have a video of some in-studio footage including a bit of one of Rivers Cuomo's guitar parts. Oh, and you get to see Rivers tweet in the video, too. Watch it above.
