Of the 10 studio releases from IQ over the past 30 years, I own the most recent 5 and have never heard the first 5. I do not own any of the compilations or live albums.

Of those most recent 5 studio albums, I was always of the belief that THE SEVENTH HOUSE was the best effort.............and although I like EVER, SUBTERRANEA, and DARK MATTER, I've been putting in some time lately with FREQUENCY (again). This most recent release from IQ really has some beautiful music.............good composition...............pretty stuff..............and flowing logic.

So, now I'm not so sure about the "best" effort............but I would definitely suggest to anyone exploring IQ music for the first time to buy FREQUENCY and THE SEVENTH HOUSE if they want to hear their better stuff.................both are excellent if you enjoy the so-called "neo-progressive" genre.
