Was 2006 the best year for post metal (and adjacent sludge genres)
Now I maybe being nostalgic, but looking at the year it felt like this year was great being an underground metal fan, primarily the year I got really into music and my iPod was poppin' off.
I saw the post in the melvins sub about 20 years since (a) senile animal. Check out other albums I remember listening to, some more than others. I was getting into proggy sludge too so I'm including them as I believe they toured together and shared fans:
My personal favourites:
Mastodon - Blood Mountain
Neurosis - Given to the Rising
Battle of Mice - A Day of Nights
Cult of Luna - Somewhere Along The Highway
Isis - In The Absence Of Truth
Russian Circles - Enter
Intronaut - Void
Mouth of the Architect - The Ties That Bind
Year of No Light - Nord
Jesu - Silver
Kylesa - TWFIW
Mogwai - Mr Beast
TWDY - Young Mountain
Kayo Dot - DAWCT
Mars Volta - Amputeture (bonus prog album)
There's probably more adjacent genres that had great releases too, indie, noise rock, folk, ambient etc too
