The counterculture movement of the 1960’s became largely about breaking the rules and making a change to better the future of Americans. This movement, more commonly known as the hippie movement, was much more widespread and arguably, more successful than its previous counterparts. This is because of its unique origins rooted in the prosperity of the 1950's and because this counterculture infiltrated every aspect of American culture through various parts of popular culture, specifically music. As music spread the ideas and appearances of the hippies, the counterculture affected music as well. This can be seen through the evolution of two mainstream rock and roll bands, The Beach Boys and the Beatles, from 1962-1969. Through an examination of changes in topics, lyrics, instrumentation, and styles of each band, one can see the great and lasting affects of the hippies on American culture.
