Katatonia has very little filler. Almost non-existent.
I do agree that there should be some material similar to Unfurl, but not the whole album. I would like to hear some of that mixed with that deeply moving and thick crunch that they do so well!! While making beautiful psychedelia, they should also be working on perfecting and strengthening that distortion, and keep pushing it to the limit (which, in their case, I see none)! Gonna be sum' good, though!
