Porcupine Tree - Oh yes... very good band. They rival Anathema in the songwriting department, but falter in emotional delivery. Regardless, songs like Waiting Phase One and Buying New Soul are wonderful prog rock masterpieces.
Green Carnation - Fairly good, but In the Woods... was a better band.
Sigh - Another great band, Hail Horror Hail is a metal classic.
Soilwork - Hmmm... slightly overrated, Dark Tranquillity is far superior.
Absu - Ugh.
Immortal - Horrible.
Thyrfing - One of the worst I've heard.
Sculptured - Pretty good Opeth influenced band.
Einherjer - HAHAHAH... this is a joke right? Hopefully...
Kalmah - Ehhh..
Lacrimas Profundere - Great Anathema clone. They lose points on originality but gain them back on delivery. The old stuff is better though, when there were black metal screeches and Elend-esque dark string based songs with growls and female vocals.
Maudlin of the Well - Ohhhhh yes. This redeems this post. Maudlin of the Well are brilliance made music.
Nagflar - Naglfar is a great techno / black metal band. Strontgorrth is one hell of an album.
Hmmmm.... some good, some horrible.
Here's more of what I discovered:
KorovaKill - absolutely insane vocals over a water based theme with chugging riffs and Arcturus-like keyboards. Recommended for those who are adventurous.
