there will always be people complaining about something or other.. i think i've heard more positive feedback about these albums than their last couple efforts for sure.
i think the afterman back to back is an amazing experience, for those who haven't heard it all, when decension comes out, listen to both records in order with headphones. it's really some of the best stuff they've ever done. there is definitely a few flaws but the records balance eachother very well. this stuff is my favorite behind IKS. gravity's union is such an amazing song, i've heard it compared to pop and radio rock... i don't think so. this is raw, gritty coheed at its best, in the vein of the crowing, one of their greatest songs!
You say that first sentence like everyone has to worship everything the band does. Coheed is my favorite band and In Keeping Secrets will likely always be my favorite record but I feel Descension is far weaker than Ascension because of the melodies and lyrics to a lot of the songs. Musically, Descension kicks ass but it isn't an instrumental albums.
