'Helter Skelter' (1968) was Paul McCartney's bid to create the Beatles' loudest, rawest rock song, a far cry from their earlier pop hits. It features crunching guitars and Ringo Starr screaming 'I got blisters on my fingers!' at the climactic end. The title 'Helter Skelter' refers to a British carnival slide, reflecting the song’s swirling, chaotic energy. Its heavy sound prefigured hard rock and heavy metal. Later, Charles Manson famously (but wrongly) claimed the song had prophetic meaning, overshadowing its true intent as simply a wild jam.
