^Exactly.
Those two songs are pretty much what Advent sounds like. The production sure isn't top notch, but it's raw and gives you a nice feeling what Opeth were a long time ago.
I like Watershed as much as you guys, but you have to admit, better production and even a little more different progression and those two songs are just as good as any other by Opeth.
Edit: I wouldn't want you people to think I'm a narrow-minded metalhead (or any metalhead for that matter). I've just always liked raw demos from bands, heavy or not. I don't love Watershed as much as other Opeth's albums just because it isn't as heavy, or anything like that. I mean, I like Coil, Burden and the love the whole Damnation album. Don't get me wrong, it's a nice record. I just prefer those two raw demos from the days.
