I'm sorry I meant "IF" current Trance tracks started becoming nostalgic sounding to bring back a thrill of 90's to early 2000's Trance.
IMO there are two parallel 'Revival' scenes right now.
The more mainstream, let by Hoffstadt/Daddy Trance, TDJ, Billy Gillies, and more is an explicit nod to the Eurodance/trance sound from the late 90s with a crowd-friendly pop direction. It's very popular though! Gillies got signed to a major label even marketing this newer direction from his older uplifting/tech style. Shugz is on the same path IIRC. No hate at all for this scene, though it's not my digs. I get why it has a huge appeal, as the tracks adapt a pop structure that is great for festival singalongs.
The more underground scene you see pimped on here by a lot of us (in the linked thread), I would argue is not specifically trying to market itself as a trance revival. A lot of the artists are inspired by the trance of old (many have said so in interviews). However, the tracks blend genres fluidly, and often do not have nearly the same melodic builds and peaks like the trance from the late 90s. Rather, they are more subtle, like stuff from 93-95, especially the stuff from Techno producers. I think many artists are careful not get too close to trance, b/c I suspect many of them, like so many of us, are rejecting modern/mainstream trance as a scene that has truly lost its way (There are some huge exceptions, like the stuff TF.R, Borderline, Forescape put out).
For me it's actually a plus, b/c while I do wish some of the underground producers would just make more fully trancey bangers, I've been mixing in adjacent but still-trancey genres a lot more than I used to and my sets have gotten more fun and interesting to my tastes. It's quite liberating to just mix what feels right, whether it be downtempo, house, techno, trance, or some variation. And it's in the spirit of the 90s trend of no one giving three fucks what genre a track is right?
