Yep, pretty good list, specially considering the source! Seems they're doing a 180 here, with Rush on the cover, and now this list! About time... Now they need to start working on a "Top 50 Italian Prog Albums"!
Of course, there'll always be people (like still-one, and KeithR) that don't like prog at all, and it's OK, we forgive them, right Ken?
With a band like Yes, Genesis, Jethro Tull, etc. it's hard to get consensus on "best album". My JT fave is "TaaB", not "Aqualung". While, for Yes, it's "Yes Album". Oh, and I disagree, we can never get enough Crimson!
Oh, and Can can get pretty weird early on, but they have some more "normal" albums, mid-to-late 70s, which could be a good starting point.
cheers,
