As we mark the fiftieth anniversary of the most momentous year in the life of the Beatles, the contributors to The Beatles, Sgt. Pepper, and the Summer of Love perform wide-ranging analyses of the group's enduring sociocultural influence and achievements.

For the Beatles, 1967 marks a signal crossroads that would both transform the group's career and place them on a trajectory towards their eventual disbandment. It was a year in which they exploded prevailing rock music demographics through the global onslaught and international success of Sgt. Pepper's Lonely Hearts Club Band beginning in June 1967. Yet it was also a period that saw them in a precarious state of flux throughout the summer and fall months, as the band attempted to recapture their artistic direction in the wake of Sgt. Pepper and the untimely death of manager Brian Epstein.

The Beatles, Sgt. Pepper, and the Summer of Love draws readers into that pivotal year in the life of the band. For the Fab Four, 1967 would see the band members part ways with psychedelia and the avant-garde through the trials and tribulations of the Magical Mystery Tour, a project that resulted in a series of classic recordings, while at the same time revealing the bandmates' aesthetic vulnerabilities and failings as would-be filmmakers and auteurs.
