A different kind of rock and roll music called surf music was being made in Southern California. Five young men from Los Angeles formed a group called the Beach Boys. Brian Wilson wrote, performed, and produced the group's records. The Beach Boys' songs had complex music and simple words. The words were about the local teenage culture. The group sang about riding surfboards on the ocean waves. One of their most popular songs was "Surfin' USA,” which used the same musical track as Chuck Berry's "Sweet Little Sixteen."
