I think Classica is one of the only albums really worth owning from this band, if you really just want to own classic shit. The songs were great compared to the other albums, my starving bambina" is one of their career's high points. This band has more in common with Opeth than Agalloch, I'd say. To me, it's as if Opeth were heavy most of the time and were more generic yet a tad more cohesive.
@wankerness...The only thing Brave murder day has in common with Opeth is of course, Akerfeldt himself. Jhva Elohem Meth ep, For Funerals to Come ep are more old school Opeth sounding and less "rockish" than the two you mentioned. I'm not saying you are, but alot of people are decieved by Brave murder day thinking it's supposed to be the best old Katatonia release. All the other releases kill it in every aspect.
