Oozing out of Seattle in the early '80s, the Melvins redefined heaviness with a slow, sludgy sound that makes you feel like you're being buried in wet cement. Over the course of their three-decade-plus career, the band have had a profound impact on mainstream grunge icons (most famously, Kurt Cobain) and underground metal acts alike. Like one of their ominous, doomy riffs, the Melvins' influence reverberates far and wide.
