At first I was like, ehrm... why? But when I played them side by side I can definitely notice the improvement. I think the clearer vocals helps a lot too. Woe was never a band that was necro by choice, but both the LPs are somewhat muddled when compared to this.
I usually never really care about remixes/remasters unless it's an album I never got my hands on to start with (like Alcest's Le Secret), but this is definitely worth it.
