Wether or not I've not listened "enough" to Mardraum is rather difficult to answer.. I still am not "finished" with that album, though I bought it when it first came out.. And to let me rephrase, or rather alter my first statment a bit.. The rest of the album is a bit boring compared to the immense "Større Enn Tid, Tyngre Enn Natt".
This doesn't exactly mean I don't like the rest of the album IMO..
It certainly has one of the best guitar sounds I've ever heard, with its "nearly out of tune" guitars..
Btw, if you like Hov, you could try out YM-stammen also, (which one of them guys in Hov are from..)..
