For my money, the essential difference with prog. was that, unlike most other genres, it was essentially 'English', not blues based and not dance orientated. Adding stuff around epic fantasy, mellotrons and long solos was peripheral. It is music that is generally less 'groove' orientated and more cerebral. The fact that there was no expectation that I would have to dance to it was a major attraction

One of the reasons Genesis appeal to me more than (for example) Yes, are the soul influences brought to the mix by Gabriel and Collins (and occasionally Banks). Of course it's all wrapped up in something quintessentially British (sic), but that warmth and groove really spice up the mix to my ears.
