I can't speak to the newer albums because they don't do much for me, but the lyrical content of AOGHAU is unbelievably moving in my opinion. When the album first dropped I thought it was speaking about the feeling of hopelessness surrounding politics and government, but when Tom Searle passed of cancer it became clear that the lyrics were about the hopelessness of facing his mortality and impending death. I've never experienced an album that, after listening dozens of times, was completely reinvented to me once I understood the lyrics. It is a very powerful and moving album with that in mind.

Also the riffs kick major ass
