Alternative rock
is a broad genre that emerged in the 1980s as a counterpoint to mainstream rock, blending diverse influences like punk, post-punk, and indie rock. Characterized by its emphasis on experimentation and emotional expression, it often features unconventional song structures and varied instrumentation. Gaining prominence in the 1990s with bands like Nirvana and Radiohead, alternative rock remains a dynamic and versatile genre that challenges and redefines traditional rock conventions.
