Beherit didn't exactly emulate its earlier works on Engram; NHV rather compiled them and infused the output with an entirely new sort of energy. The new DCD album is, in a way, similar. Sure, the old albums are classics, but touring isn't about the quality of output as much as conveying a feeling of wonder. It stands to reason that Perry would rather play his new stuff, regardless of its quality, rather than perform as a has-been and play all of the stuff everyone knows and can clap to.
A has-been burnout isn't exactly the best source of honest wonder, and given that Anastasis is more Spleen and Idealish than Spiritchaserish in its structure, DCD eschewing their older works to play something "dead that dances" sounds pretty good overall.
(Then again, the Beherit comparison was pretty arbitrary. I'd rather think of the new DCD material as a sort of CF's Monotheist. Much better than their "recent" output, and, all in all, you prefer its "industrial nu-metal goth" honesty to the retro-reconstruction of Triptykon).
