Skydance change my standards for progressive metal (it was the same era that i've known Opeth too). It was something different with harmonies flowing smoothly pushing the leads ahead into your soul, and manuevers that put a smile on your face. and dont forget the lyrics.
However, it didnt end there - as The Gallery, although a bit different, kept that flame and was as a whole, even better.
But than DT broke my heart. Many bands walked their way, and Opeth in their own path progressed further. But DT wanted to change their motif to something more streaming maybe, or more consensual but less progressive, and in my opinion, nothing special. Generaly i dont keep a favor for bands only because the name is the same - but also dont stop following to see what's new. If a band stops being intresting for me, i dont buy it anymore (of course they can buy me again in the future, if sound changes) - DT turned such when i bought The Mind's I. It introduced few progressive tracks, but most of the CD wasnt my test anymore. They were interviewed saying it was their direction for a while, being less progressive more metalistic. I dont know about you fellows, but Skydancer and Gallery were genuine creations.
I think new people introduced with DT should listen to both those records in order to urge for something like that again.
