The self-titled is pretty class, but DSEV is... eh. As big of a Burzum fanboi I am, I only really like a couple tracks on it. :/
I cannot explain it for the life of me but some albums have some sort of a strange nostalgic quality to them. Listening to them reminds me of something, it's like feelings of deja vu but I do not know where or of what specifically. They just manage to remind of feelings, imagery, thoughts, or dreams I had from much earlier times in my life like before I was even into music. Even a simple track like "Han Som Reiste." Maybe the cheap synth sound used there appeals to me but the self-titled album and Det Som Engang Var I find are quite atmospheric despite not having the more prominent synth use of later Burzum albums. But the self-titled album is probably my favourite.
