Grunge is a rock music genre and subculture that emerged as underground music during the mid-1980s in the Northwest US state of Washington, particularly in Seattle. The word "grunge" is American slang for "someone or something that is repugnant" and also for "dirt". It flourished in the late 1980s and early ’90s. The term “grunge” was first used to describe the murky-guitar bands that emerged from Seattle in the late 1980s. Grunge artists were influenced by heavy metal, hard rock and post punk alternative rock. Grunge fuses elements of punk rock, heavy metal, hard rock and post punk alternative rock. This genre is characterized by distorted electric guitar sounds. The typical instruments of grunge are the electric guitar, the bass guitar, the drums and vocals. Grunge lyrics are typically angst-filled and introspective, often dealing with themes such as social alienation, self-doubt, abuse, betrayal, social and emotional isolation, psychological trauma and a desire for freedom.The most representative bands of this genre of music were Nirvana, Pearl Jam, Soundgarden, Alice in Chains and Stone Temple Pilots. During the mid-to-late 1990s grunge declined and many grunge bands broke up or became less visible.
