The instruments don't really drown out the vocals, they just have a more prominent presence in the mix. I have no problem with that. The instrumentation is beautiful, and they were definitely going for a more atmospheric, post-rock-ish tone with this one.
The new album was okay for me. There seemed to be less passion overall, fewer songs that I could really get into. For example, songs like Lower Still and Perfector on the last record were quite amazing. My biggest issue with the record, though, is the mixing. The guitars are too loud and drown out the vocals a lot of the time. Not sure what they were thinking there. A heavier record is fine, but it has to be balanced. "Yet" is still their best for me.
I don't hear or look at their music as organised Christian beliefs but life in general. Their music has a strong human element that the harmonies and melodic music itself comes from. That stems from the heart and soul of this band and their passion for music. Behold is a masterpiece btw.
I love seeing people complain about these guys being religious. Who cares? I don't listen to non-religious music and think "if only this was religious." It's the way they chose to do their music and the way they chose to craft their art.
Usually I don't care much about the lyrics to songs. But I love the words these guys write. I think Lower Still (with Beloved in close second place) have my favorite lyrics of any songs I've ever heard.
