04:50 - The Maratha Also, black powerfully blending with genres of death, drone, psychedelic, doom, sludge and so on. More or less, this past 2 years there has been a trend of experimentation in metal altogether.
04:44 - The Maratha The problem is that Sludge creepingly blends into heavy, doom, black and death. Look at Roadburn for instance.
03:24 - Marcel Hubregtse SLudge is actually already dead since most bands in that genre are copying each other . Savannah SLudge is doing it and so are the others. If you hear mrore than 6 new sludge bands each months you will notice it.
02:29 - Apothecary Yeah you have a point, that "only old school is real, modern bands suck" mentality is still pretty strong among parts of the metal community though, unfortunately
Such a great list needs to be commented on. Not that I have much to say at this point since you seem to have your bases covered. I didn't know there was an Undersmile split, must check that out asap.
That split is really interesting seeing as Coma Wall is an acoustic project by the members of Undersmile which makes for a nice contrast to their usual bone crushing sound that is presented on the second half of it.
