It's true they got heavier on in absentia, but the amount of heaviness is relatively comprable since. FoaBP has softer songs like my ashes, and sentimental so it still has DYNAMICS from softer to heavier, which is the most important thing about a cd(not just heaviness.) There's not one song on here that rises above the heaviness of the past two releases, and if you were looking for darker heavier moments then In Absentia goes to their most extremes at times. I don't know why this should be a subject because this is just a small aspect of what makes the music good. I think FoaBP is a great release because it has the best production(their fullest yet is what I think people mean to say) the songs are solid, and the most progressive(since older records) longer songs without feeling drawn out, very catchy(in-fact I find this to be their catchiest release yet), and it's still a very dark album. But I think a fan of katatonia, and anathema will most certainly like In Absentia the best. So I'd say go with In Absentia then FoaBP.
