Personally I don't demand albums from the artists I'm listening to, but looking at Tool's last couple of years since 10k Days was released, they have pretty much been touring around the same cities in the states, playing a fairly standard setlist with maybe a few songs swapped.
I'm not disappointed in the band or anything like that, because obviously they do whatever they want, and I understand that. It feels a bit weird though, because it doesn't feel like the band themselves has the "glow" anymore. Sure they are still together and they have yet another US-tour now, but they don't seem too excited about making a new record, the four they have seem to be enough, and they seem happy enough just touring those songs for the next 10 years making money from them.
That's how it feels at least. When someone in Tool says "we will start working on a new album", that generally means that maybe somewhere down the road, ~2 years into the future we might get an album, but most likely not.
Or maybe I'm just frustrated because they tour in the states, then another tour in the states, and then another, and they haven't played in Europe in a while, at least not near me. I would love to see them live, but seeing as that won't be likely (unless I go to the states), another album is high up.
