Creedence Clearwater Revival was an American rock band active in the late 1960s and early 1970s. The band consisted of lead vocalist, lead guitarist, and primary songwriter John Fogerty, his brother rhythm guitarist Tom Fogerty, bassist Stu Cook and drummer Doug Clifford. Their musical style encompassed the roots rock, swamp rock, and blues rock genres. Despite their San Francisco Bay Area origins, they played in a Southern rock style, with lyrics about bayous, catfish, the Mississippi River, and other popular elements of Southern United States iconography, as well as political and socially-conscious lyrics about topics including the Vietnam War. The band performed at 1969's famed Woodstock Festival. The band has sold 26 million albums in the United States alone. Rolling Stone ranked the band 82nd on its list of the 100 greatest artists of all time.
