Stoner metal
Stoner metal or sludge metal is a type of heavy metal music which gained popularity in the 1990's, but has predecessors as early as the 1960's.
Stoner Metal and Sludge Metal are often used interchangable, but some fans make distictions: Sludge metal has more connections with grindcore and hardcore punk. There also are similarities to doom metal, but some fans consider the two genres distinct. Other terms, which also indicate slightly different genres of music are 'stoner rock', 'desert rock' and the very abstract 'desert music'.
Stoner metal bands play a mix of jam-heavy psychedelic rock laced with some doom metal like riffs and are generally more closely linked to the heavy psychedelic bands of the late 1960s and early 1970s. Monster Magnet and Kyuss were among the most popular practitioners
