During my season rewatch, the music leapt out at me in a way that I didn't notice the first time. Since then I've asked Alexa to play the Disco soundtrack a few times just to soak in it.
I am a big fan of new-era Battlestar Galactica, not least for its fantastic music by Bear McCreary, and I hear a lot of echos of that in Disco: lots of drums and "eastern" influences like reed-flute. And in the more "traditional" symphonic-sci-fi vein I hear an echo of the JJ-era Trek film scores by Michael Giacchino, which I also love.
Elsewhere in these forums, people have rated their favorite Trek show theme musicks. I'm a sucker for the traditional big-orchestra symphonic movie soundtrack style, so I would say: TNG, TOS, DIS, DS9, VOY, ENT.
As an aside, I have a personal obsession with the DS9 theme, and how it reflects the heights of cultural power that Star Trek held when the series came out. It's so gentle and contemplative, which is something a new show trying to prove its bona fides would never try to pull off. I once saw the DS9 theme performed live by an orchestra in Denver at an outdoor show that I just happened to be walking by; and it was remarkably powerful music! I was moved close to tears with the opening notes played by French horns. (And it's just funny that the main theme is played by tiny piccolo trumpets.) I'm a lifelong Trekkie and even I was surprised by my emotional response!
Ah, of course, the performing arts complex makes way more sense. I've seen a lot of opera there and a few musicals (none of them Rent, though!).
I don't think I had realized that BSG had altered it's theme between the first two seasons. DS9 does this for Season Four (I think), and Enterprise does it at Season 3 -- both to make the theme more upbeat. But I think I prefer the earlier versions of both themes, and I'm not sure why the networks feel they should have exciting theme songs.
Actually, now that I think about it, the first-season BSG theme was also really understated, which was one of the things that impressed me about the series. They re-did it for the subsequent seasons to be a bit more in-your-face (but not much!).
I was also surprised when I asked Alexa to play Star Trek Discovery and it actually worked! Every other general "Star Trek" query I made ended up with the JJ movies.
I confess that Enterprise is the series I'm least familiar with. It's the only one I didn't make it all the way through. I can totally see how the theme would be whistlable!
The concert I stumbled across was the Denver Brass something something at the big arts pavilion place. This was a couple of years ago when I was there for a conference.
I feel like a fool for not realizing the first-season score was already available. I will rectify this as soon as I'm done typing.
I thought the music did a great job of playing with the location. It sounded a little different to me when we were on a Klingon ship or in the Mirror Universe, and even a little different in the premiere. But I especially like that the theme music makes me think of people working in a lab or building something. Perhaps I'm the only one, but it sounds the most sciencey of the Trek themes.
I love this reading of the DS9 theme, which remains my least-favorite of them (though still much-loved). I'm not quite ready to place Discovery's theme on the list just yet, but I'd probably put it around the middle as well. My wife's initial response to the Enterprise theme was derision, but I've been catching her singing it, so I think it's fair to say that she's on board.
P.S. I lived in Denver for ten years and I'm curious about which park you heard the DS9 theme at.
