Punk rock bands emerged in the 1970s as a reaction against the mainstream music scene, characterized by their fast tempos, simple melodies, and rebellious lyrics. Bands like The Ramones and Sex Pistols played a crucial role in shaping the genre, influencing countless musicians and subcultures worldwide. The punk rock movement also gave rise to various subgenres, including Hardcore Punk and Pop Punk. These bands often address social and political issues, using their music as a platform for change. The DIY ethic prevalent in punk culture encourages bands to produce their own music and promote their shows independently.
