Is Styx album The Grand Illusion prog?

Sufficiently prog to get a yes. My favourite album by them. Always thought the term pomp rock was an attempt to include bands like this with a proggy influences over a more mainstream rock foundation.

I lean more towards yes.

I think Styx is prog in Equinox, Crystal Ball,The Grand Ilusion and Pieces of Eight. but , The Grand Illlusion is really their great prog moment !

OK album with some stylings borrowed from the usual suspects.  To me it's '70s era rock album with a prog arrangement that was more or less fashionable at the time. But there is nothing in the realm of say And You And I. It was merely a way of performing the songs which could have been done as disco number they were so essentially generic. Could've been Saturday Night Fever contenders.

Moreover prog rock is an essential composite of classical scope and detail using rock to drive the dynamics. Illusion doesn't really do any of this. I found it disappointing - which is made worse as I had little expectation in the first place.

Some of the other albums before it are more listenable to me as rock pieces never mind prog rock.

I know AOR is a format rather than a style but this seems to be the orientation (rather than musical direction) of Styx - and where they were very successful.

Equinox

Most (all?) of the Wooden Nickel stuff is much proggier than anything that came after.

Yes

I would say, maybe. But not as much as Pieces of Eight.

Castle Walls was prog. I'm not sure about the rest. Come sail away was proggish especially with the synths. Great album regardless. I can't really decide so I won't vote.

I'd say that Styx's proggiest album (by far) is their debut... But it's clearly the worst prog album ever recorded

I enjoyed immensely their albums from Equinox to Po8, but let's face, there was the odd proggy track (like Castle Walls), but the rest was brilliant pomp-rock
