Country music is the sound of America's heartland, with roots in traditional Folk, as well as in the hillbilly sounds of Appalachia. It is characterized mostly by its lyrical content - heartbreak, loss, cheating - and a distinctive twang. Country encompasses everything from the Honky-Tonk of Hank Williams, to the Bluegrass Folk of Bill Monroe, to New Country superstars Garth Brooks & Shania Twain.
