Frank Zappa, the boundary-pushing bandleader of the Mothers of Invention, was a lifelong "cultural contrarian" who avoided drugs and drink even as fans assumed he embodied 1960s West Coast psychedelia. This context shapes why he later took issue with The Beatles, particularly around the time of "Sgt. Pepper's Lonely Hearts Club Band", as he viewed their mass appeal partly through a lens of calculated marketability rather than pure artistic risk-taking.

In a 1968 essay for Life magazine, Zappa praised The Beatles' early energy and their ability to speak directly to young people, but also argued that their success rested on being "cute, safe, and white". He saw cuteness as a factor entirely separate from musical talent yet crucial to commercial success, a tension that came to a head when the band shed their clean-cut image in 1967, growing hair and beards similar to his own and repositioning themselves as more experimental artists.
