The thing that makes me so pumped about it is that this is Rush's first concept album (2112, Hemisphers, and Caress of Steel all have sidelong epics, but none are complete
albums dominated by one theme, idea, or story), and from they're own words, they're going for the more ambitious, "out there" style that they had in the 70's and early 80's, which made me a lifelong fan. It just excites me to see them be this bold and imaginative again, producing a true-to-form prog rock concept album with an orchestra in a time when prog has been left for dead by many, the ipod/itunes has almost made the "album" a lost art, and there is "all this machinery making modern music", spitting out crappy pop singles to dominate the airwaves.
and of course, just from hearing "Caravan", and the 30 second clip of "Headlong Flight", I can hear a roaring, heavy, dense sound that they haven't boasted in a long time; a powerful sound that only comes from a power trio in proper form.
Plus, it's a new Rush album. What more really needs to be said?
