Led Zeppelin emerged from the British rock scene in 1968 and fundamentally reshaped how electric guitar, bass, and drums could function together in popular music. Their catalog draws from blues traditions, folk sources, and Eastern music, filtered through a sound that was heavier, slower, and more deliberately crafted than most rock music of their era. The band's influence on metal, hard rock, and progressive music remains inescapable nearly five decades after their final performance.
