Music without a click track? If you want that, see or hear or buy a live DT album. I think MP states that he's never used a click track in a live setting (until later this summer with A7X), so that means that DT plays live without a click, which, if you want something raw and with more HUMAN feeling in it, rather than sticking to a click track, that's what a live show is for.
To me, using a click track is the rhythmic equivalent to using a tuner for melodic/harmonic purposes. It's just one way to make sure the music stays together, be it in time or in tune, and it allows all the parts of a song to come together nicely, and in line, and makes editing easier, be it as a whole song or individual tracks (especially when you are working with 20+ tracks for different sounds or instruments). Besides, I think using a click in studio helps them create the music they hear, and want us to hear, especially if it can't be recreated live (due to layering or otherwise lack of instrumentalists).
Now if they used a click ALL the time, in the studio and on stage, I would be concerned, but I don't know of too many bands (particularly prog), who use click tracks during their live shows - the music lends itself to be memorized and played organically at times, due to the nature of some prog bands/music. But for bands like A7X and others, they probably use clicks for triggering things on time, which is understandable - you don't want to miss triggering something if the band is going slowly or too fast, or you just aren't paying attention.
