Even the first one without Dennis, Cyclorama, had some great stuff. Okay, it's not that consistent, but I would say half of it is at least good, and One with Everything is easily one of the best songs the band has ever done. I love These are the Times as well (one of the best Styx songs where JY sings lead).
Cyclorama has to be one of the most inconsistent albums I've ever heard in my life. There are some truly terrible songs on there, plus a handful of good ballads and pop-rock tracks, and then -- as you mention -- One With Everything, which is simply incredible in a Styx-by-way-of-Spock's-Beard kind of manner. Lucky enough to see it performed in concert once. Amazing song.
I really love The Mission. Not sure it's a masterpiece, but it's far better than I thought a Styx album getting released in 2017 had any right to be. It's a really compact album, and I actually kind of think it's a little
too short. There are a few themes, both lyrical and musical, that I wouldn't have mind seeing developed a little further. But the run from Locomotive to The Outpost is pretty much flawless. The story is quite good, too, especially once you realize that their titular "mission to Mars" is actually a lot more than just that...
