Scenes is a far more technical album than this one imo...
Beyond this life, strange deja vu, home has some absolutely insane parts, the dance of eternity.... Beyond that, they also had the lyrical technicalities. So yeah, it's a technical album for sure, but not the most technical. I'm not sure where it would rank for me yet.. Definitely below SFAM and 8VM. 8VM might have just been their most technical on the big giant nugget scale.
Also 6DOIT is more technical.. I consider technical to consist of lyrics as well.
