Sludge metal (aka Sludge Doom) is a genre of metal that takes inspiration from Doom Metal. Sludge is kind of like the raunchy cousin of Doom. Sludge is very prominent in the South, many of the earliest bands on the scene began there (particularly in New Orleans area) such as Eyehategod. Sludge metal is typically more aggressive than doom, taking inspiration from punk (indeed members of EHG and Down formed Crust punk band Arson Anthem). Lyrical content generally focuses around suffering, drug and alcohol abuse, and politics. Some bands include:
The Melvins
Superjoint Ritual
Weedeater
Buzzov*en
Eyehategod
Rwake (pronounced 'Wake')
Down
Isis
Neurosis
Jesu
Baroness
Crowbar
And many others. Bands such as The Melvins have been credited to have first touched on and inspired the sludge sound, and Eyehategod is generally credited to have broken the scene open.

Like it's counterpart doom, sludge is another genre of "music" inspired by Black Sabbath. Unlike doom however, which emphasizes slower tempos and dynamic heavy riffs. Sludge emphasizes even slower tempos, repetition and progression.
