"I love it! To me it seems like a good successor of Lateralus - some tracks are as ambitioned and abstract, others are less tense and and even a bit mellow, reminding of Aenima. I really like the epic of the album - tracks #3 and #4. They're really gloomy and sort of depressing - Maynard never explains the lyrics, but I'm sure they are mostly about his mother, but might also include other topics.
I think that I'll prefer this to Lateralus in the long run - somehow 10,000 Days feels more balanced to me, but it's really too early for a final verdict."
