Sleep

Sleep is an American metal band formed in 1990 known for slow, heavy, riff-based music that blends doom metal textures with psychedelic and stoner rock elements. Their sound emphasizes long, droning riffs, extended song structures, and a thick, fuzzed guitar tone, and their lyrics and imagery often reference cannabis and occult themes. They are associated with the development of the stoner doom subgenre and are noted for marathon-length compositions in both studio recordings and live performances.
