Hard rock is a genre of music that emerged in the late 1960s, characterized by its powerful sound and energetic performances. It often features loud electric guitars, punchy drums, and strong vocals, creating anthemic melodies that resonate with audiences. Bands like Led Zeppelin, Deep Purple, and AC/DC pioneered this genre, blending blues influences with a heavier edge. Hard rock has evolved over the decades, inspiring many subgenres and continuing to captivate listeners around the world with its raw intensity and rebellious spirit.
