Way more in common with Six Degrees than with Falling Into Infinity, which is quite a feat given that half of it was written during the FII sessions.
So yeah, next era, far-and-away. Although, given the size their catalogue's reaching, the eras are starting to split a little deeper than old-and-new. They've got more than two phases, I'd say. Something like...
1. Dream and Day
2. Images and Words
3. Awake
4. Falling Into Infinity
5. Scenes from a Memory
6. Six Degrees of Inner Turbulence
7. Train of Thought
8. Octavarium
9. Systematic Chaos
10. Black Clouds & Silver Linings
11. A Dramatic Turn of Events
...yeah, think they're the logical splits. I'm not entirely sure what they're split into, but they all feel like bedfellows. I guess... the common themes are er, something like invention, experimentation, groove, and future? Although that does sound like a shit remake of the Crystal Maze.
