For those that like your doom, grand and lethargic yet melodic check these Swedes. I personally don't do doom as such but I like Candlemass mostly and some Solitude Aeturnus. I like the singer in this Swedish band. His voice is smooth and melodic and Ozzy-esque somewhat but with a nicer tone. I also hear some Cathedral groove riffing in their sound so if you miss Cathedral then give it a try.
