Each of the kalmah albums have something to offer, I personally really like about half the songs off each album, regardless of their differences (which aren't as much as some would have you believe).. it's a pretty logical progression if you ask me..
Try:
Swamplord: Evil In You
Swamplord: Withering Away
They Will Return: Swamphell
They Will Return: Human Fates
Swampsong: Doubtful About It All
Swampsong: The Third, The Magical
Oh yeah, and that Mons Pubis (wtf is their name again? I forget it after 2 minutes!) band is pretty good from the clips on their site.. They just REALLY REALLY REALLY need to change their name.. I mean that kind of thing can hold a band back from getting well known.. How can people talk about you if they can't remember your name?? Oh and, Norther sucks (in my humble lowly opinion). Their music can be OK, but it's really nothing that stands out.. and have you seen their videos? They just stand there like statues and the singer is smiling while he's supposed to be screaming angrily.. So I guess you could say he looks gay, hey don't get offended I only mean he looks very happy!
