I haven't read all the replies to this thread, but from Erik's original post... I just have a couple of thoughts.
1. Doom is awesome, and seems to be the kind of thing that will stay in the background, producing great albums but never taking over or becoming the "future of metal". It's great now, it's been great since Sabbath, Candlemass etc. and it's quite fucking diverse. Cheers to doom!
2. I very much agree with the guy (possibly JK, possibly not) who said that doom riffs get an emotional response out of people regardless of whether people identify them as "doom" or not. Works for me, anyway.
3. People likely said the same things about black metal and death metal back in the late 80s/early 90s (I'm too new to this shit to know what it was like back then). Who knows what'll happen in the future, and frankly, who cares? All this over-analysing is pretty worthless if you ask me. True innovation doesn't come from trying too fucking hard to make things weird and experimental. Often enough, that leads to "noise" or some kind of wankery. I don't know if this dissecting-everything and trying-to-force-innovation attitude is a recent development in art, or if it's been around from the beginning, but I don't like it.
