progressive became a genre in and of itself is somewhat of a mystery to me
"Progressive" is an abbreviation of "progressive house". They aren't different things.
The variations in what "progressive house" is depends on which direction you come from.
Personally, I was very much into the US style of prog (Tenaglia, DJ Vibe etc which later became Lawler etc) which had lots of tribal and sometimes techno influences but little from trance generally. Other kiwi prog DJs - who killed the scene by basically playing soft trance, prog based on a more cheesy ideal - came from the European/UK version which was more like Tilt, Sasha, Hooj etc. Much more synthy and overall much closer to trance.
This is where prog trance spun out of imo as people in this group matured and found common ground from trance people moving towards their sound at the same time.
Interesting that the US, broader influences, sound still exists big-time (Digweed, Howells, Tenaglia etc) and even in UK with labels like Bedrock... yet the more European sound has disappeared with the advent of synthy electro/minimal etc. If you look at the DJs who played it you can see this too: Sasha etc.
I wonder if the biggest difference in dance music on the two sides of the Atlantic was in their history. The US was more about subtlety and soulfulness whereas the UK was more about in-yer-face party. Ironic that two of the most significant clubs in UK clubbing history - The Hacienda and MOS -
both were very American influenced in their sound. Almost as if the people (now regarded as visionaries) could see the longevity in the US sound as opposed to the hit/anthem dominated UK style.
It could be a good lesson for clubs still imo. Here and elsewhere.
