I'm most of the way through Disc 3 now. It included exactly the cue from Debney's "The Nagus" that I remembered liking, though unfortunately, as is so often the case, my memory exaggerated how much I liked it.
I've listened to all the Bell contributions, and I like them. Yes, there's a certain sameness to it, but I find I like to listen to it nonetheless. It surprised me, though, that Bell's characteristic use of 3/4 time didn't emerge until the "Sacrifice of Angels" segment.
I do wish there'd been a longer selection from "The Sword of Kahless." I really love Bell's leitmotif for the sword, and it was nice to get one good iteration of it in the closing cue, but I would've liked more. I also regret that Bell's Klingon opera source cues aren't included. But I'm really glad my favorite cue from "Take Me Out to the Holosuite" was there.
