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

The lack of blues influences was the main thing that I loved about prog, that and the "Englishness" of it, the same reasons I love traditional English folk music.
