Description: Grunge is a genre of alternative rock that originated in the Seattle music scene in the late 1980s and gained mainstream popularity in the early 1990s. Characterized by a raw and unpolished sound, grunge often features distorted guitars, anguished vocals, and lyrics that often reflect themes of disillusionment and introspection. Key bands associated with the grunge movement include Nirvana, Pearl Jam, Soundgarden, and Alice in Chains. Nirvana's breakthrough with their album "Nevermind" in 1991 is often considered a defining moment for the genre. Grunge music is often linked to a DIY ethos, rejecting the overly produced sound of mainstream rock at the time. Grunge had a significant impact on the music industry, influencing fashion, attitudes, and the broader alternative rock movement. While its popularity waned in the mid-1990s, grunge remains an important chapter in the history of rock music.
