What's the difference between sludge metal and grunge?

Well I'd say the big differnces are....

The Speed... A lot of Sludge Metal songs tend to be slower paced because it shares certain musical characteristics with Doom Metal (which is really just a slower paced version of Gothic Metal). Many of the songs seem faster than they really are because of the distortion, the reoccurence of notes, bassline, and drumming. Although their are very fast songs and those songs seem to just fly by due to the intense pace.

Atmosphere... Sludge metal is a lot more atmospheric than grunge bands (another similarity to Doom Metal and Gothic Metal).

Structure... Grunge generally goes from slow (verses) to fast (bridge/chorus). Sludge Metal generally stays at a regular speed, but when they do speed up they don't speed up by a lot.

Aside from that... There are also many lyrical differences between the two, sludge metal is more technical, more psychedlic influences in sludge metal, more feedback in sludge metal, and the presentation of grunge is a lot dirtier than sludge metal (go figure).

Isn't Sludge Metal stuff like Monster Magnet and Sunn O)) and Boris?

Or is that Drone Metal, whatever it's mostly the same stuff.

I think Sludge Metal just sounds cooler than Grunge in comparison, but it's mostly the same stuff. I know White Zombie is Groove Metal, but they were a really cool band as well, and they could of even counted for Sludge Metal.

Sludge metal has elements of doom metal and stoner rock, and it's darker and heavier than grunge.

ew they both sound totally grodie!!
