Their fourth album, and the first to feature the plodding, superlong songs they were to become known for, Bullhead remains a defining moment for the Melvins, grunge and stoner metal all at once. The avant-metal Japanese band Boris took their name from the impossibly perfect opening cut on this album, and there are few moments where the listener is given even a second to relax. This is the sound of pothead kids taking Black Sabbath to extremes never even thought of before. Thank God for the Melvins.
