So, tell me about Primordial...

"A Journey's End" is easily their best. Listen to the title-track and "Autumn's Ablaze".

As for similar artists, I've never heard anyone, and I guess that's one of the things that make them so great!
 
"Spirit the Earth Aflame" is widely considered their best achievement, and it sure contains some classics. But I would have to agree with Crimson Velvet that "A Journey's End" is ultimately their most rewarding effort when it comes to thoroughness, feeling and intensity. It needs more spins than the rest. "Storm Before Calm" is very good, just not quite top-notch. Same goes for "The Gathering Wilderness".
 
"Storm Before Calm" is indeed good, but I found it too be very inconsistent. A lot of boring tracks there. But I do consider "Sons of the Morrigan" to be their best track ever!
 
It's funny because a lot of the time, I tend to cling to the first album that really sold me on a band (in this case, Spirit the Earth Aflame). But over the last couple of years, I've listened to a ton of Primordial and I honestly think The Gathering Wilderness could be their best effort yet, followed closely by A Journeys End.

Overall though, TGW, StEA, and AJE are all MUST HAVEs (the difference between the three is almost negligble). Everything else is secondary.

Great band and pretty much the core reason for me flying to Heathen Crusade.

Similar Artists: Nobody really, but check out Destroyer 666 and Drudkh's Autumn Aurora (all extreme vocals however). Of course, Nemtheanga is a huge selling point for Primordial so you might also want to listen to Void of Silence ("Human Antithesis").
 
I finally clicked with Primordial yesterday. While standing at the front of the ferry wind in my face, balls freezing off watching the clouds. I'll upload pictures later.
