One of the most frequently misunderstood genres of popular music, heavy metal traces its origins back to the late 1960s, as the hippie movement began to burn out and hard/acid rock bands began to proliferate, bringing with them a new, hard-edged style of guitar playing. For instance, many consider The Beatles' "Helter Skelter" the first heavy metal song while the electric guitar legend, Jimi Hendrix, is credited as a major inspiration with the story that a supposed music magazine article described his music as "like bars of metal raining down on the stage."
