From John Lennon’s opening guitar crunch of “Revolution” to the dizzying psychedelic wind-up of “Tomorrow Never Knows”, this exclusive album collects The Beatles’ songs that rock the hardest. The early power of “I’m Down” only hints at the band’s colossal statement of heaviness with “Helter Skelter”—a song that came well before Zeppelin and AC/DC fully powered up. The stripped-down rock and soul of “I’ve Got a Feeling” is set up with mid-period FM radio rockers like “Paperback Writer” and “And Your Bird Can Sing”.
