Structurally complex rock music often with baroque and classical influences and thematic cycles of song writing that relies on very skilled techniques from the musicians.

To me putting "progressive" in front of a genre just means you're taking said genre forward into new, (often more "sophisticated", for lack of better word) directions. it's often more artsy (edit: and I forgot to say complex) but I don't think more technicality is a requirement.

I'd say post-hardcore is more expirimental than it is progressive, it either emerged from or was inspired by the hardcore scene, and used hardcore as a groundwork but did whatever the **** they want with it as opposed to staying with it's many limitations. It doesn't really seem to care for bringing punk forward, but they're just using it as a template and express themselves more freely than they could if they'd stay within it's boundaries. Many post-hardcore bands are doing their own thing, while progressive rock bands are really trying to bring rock forward. I would say it shares that characteristic of often being more "sophisticated", though, and has a similar role as a subgenre.

This is exactly why I consider Pink Floyd prog, that and they followed/created/pioneered many of the same tradiotions various prog bands follwed back then and in the future. I guess they were as prog as the others because prog was still being formed then. But if Pink Floyd ain't sophisticated and artsy...
