Grunge music emerged in the late 1980s and early 1990s, primarily in Seattle. It blends elements of punk rock and heavy metal, characterized by its raw sound, heavy guitar riffs, and emotionally charged lyrics. The genre often addresses themes of disillusionment, alienation, and social issues, resonating with a generation seeking authenticity. Key bands associated with grunge include Nirvana, Pearl Jam, and Soundgarden. The genre gained mainstream popularity with the release of Nirvana's album Nevermind in 1991, which helped define the sound of the era. Grunge's influence can still be seen in various music styles today.
