“Sgt. Pepper’s,” you see, is the album that marked the shift in rock music away from the grubby fingers of the teenybopper crowd and into the hushed halls of Great Art. It was the transition album that turned rock from a debased music for ponytailed fans twisting the night away to music for grown men whose tastes are far too refined to worry about whether a pop song has a beat you can dance to.
“Sgt. Pepper’s” was the point when rock stopped being the music of girls and started being the music of men.
