I haven't been able to put down the newest release from Tool since I got it. The opening track, "Vicarious" has an odd time signature - 10 beats per measure instead of the expected 8. The resulting feeling is one of incompleteness, as every measure seems to end with the beginning of another, unfinished one. I can't think of a cooler way to start out your album - and it just gets better from there. There's also a really neat pair of stereoscopic goggles built right in to the CD case, which you can use to view the outstanding original artwork included in this release.
