10,000 days aged well for me. i was disappointed when it came out because i was expecting aggressive music with psychological and spiritual themes like the previous albums had, but those aspects that me and a lot of other fans were anticipating were the things the band changed, withdrawing a lot of aggression and making the lyrics much more mundane. it's an odd album that can't be categorized, though words like tribal, punk, and experimental somewhat describe it. as usual danny carey is phenomenal, adam jones makes the guitar visual like no one else, and maynard does his most elaborate filtering/layering yet, and delivers a flooring performance on the title track(s). it's a rich tapestry. if it weren't the latest tool album, but just the first release from some unknown band, it would be considered a marvel. it has a deep brooding vibe that i can't compare to anything else musically, and the bass is outstanding, it's a top 10 bass album for sure.
