There are a few that comes close, Porcupine Tree and Anathema for example, but I don't really care for either band's debut album (apart from a few songs). Opeth has a few songs from the earlier days that don't do that much for me, there are several bands that comes pretty close actually, I just narrowed it down a bit.
