New Orleans' Crowbar are one of the defining bands of American sludge metal, building their reputation on crushingly slow tempos, emotionally raw vocals, and riffs heavy enough to bend steel.

Boston's Crowfeeder channels the bleak introspection of post-metal through a sludge lens, building slow, towering structures out of distorted guitars and atmospheric tension. Their music rewards patient listening with a sense of weight that accumulates over time.
