The Beatles tower over popular music unlike any other band. Everyone knows their name, everyone can hum at least a few bars of one of their songs, and I’m willing to bet that a great deal of people could name each of the band’s four members. The Beatles’ massive popularity is interesting for a few reasons, not least of which is that an act that served as such a monolithic part of pop culture could be so bloody weird throughout its career. The band’s early years, playing Americana rock songs in Hamburg and reaching superstardom with sugary pop albums, may have given The Beatles an enormous fan base, but what’s most fascinating is that, after becoming the biggest band of their time, they embarked on a career of intense experimentation. The smiling melodies of Help! gave way to the eclectic sounds of Rubber Soul, Sgt. Pepper’s Lonely Hearts Club Band, and Abbey Road.
