I think all these guys had their day. But their days are gone. And trance is dying because all these guys are killing it with progressive.
To bad when newcomers in EDM search for "Trance" they get artists like these above which mainly creates mainstream and commercial tracks now, tracks which have nothing to do with trance. Then they get ASOT, Club Life etc. to know which are just getting worse every week, playing g*d damn pop now!
In many ways trance is evolving, it has done that since the millenium and that is great, but when people just listen to tracks with lyrics like "Oh oh oh, I cut myself, oh oh oh" with random beats they just listen to "pop-trance".
True, these artists had their time, now they pretty much suck, that's why we have Afterhours, still playing great, modern trance, also with more unknown artists.
Trance was way better 10-15 years ago, but todays trance is great as well. Just don't search for "trance" on google, you'll just get some pretty damn bad producers/dj's
