Southern rock is a subgenre of rock music and a genre of Americana. It developed in the Southern United States from rock and roll, country music, and blues, and is focused generally on electric guitar and vocals. Although the origin of the term southern rock is unknown, "many people feel that these important contributors to the development of rock and roll have been minimized in rock's history."
