We heard a live version of the promising new Weezer song “Back To The Shack,” and now, we’ve got an additional reason to once again foolishly get our hopes up (and I say this as someone who liked Hurley). Weezer just leaked a 20-second clip of new music — mostly just bits of riffs — along with the note that they’re “in the studio now.” It’s 20 random seconds, so let’s not get crazy here, but it’s a great-sounding 20 seconds. Check it out.
