I see their career trajectory as being very similar to Metallica.
Remission and Kill are both the aggressive debuts.
Leviathan and Ride are both the more mature follow up
Blood Mountain and Master are both another step up.
Crack The Skye and Justice are both the 'proggy' ones with long songs.
The Hunter and Metallica are both the pristine sounding big rock albums that are slightly more commercial.
Once More Round The Sun and Emperoer Of Sand would be their Load & Reload.
But it looks like they wisely skipped St Anger and Death Magnetic and went straight to their 2 CD double album
They even put out an EP of album leftovers called Cold Dark Place - which is obviously way better than Beyond Magnetic.
Interesting.
