Patrick Sky was one of the most enigmatic performers of 1960s folk music. With Creek Indian and Irish ancestry, Sky first attracted attention singing the traditional folk songs that he learned from a grandmother as a child. Sky was equally influenced by the satirical writing of Will Rogers and the topical songs of Woody Guthrie. Beginning with his recordings of the late '60s, Sky's songs became increasingly political and outspoken. Sky's most confrontational album, Songs That Made America Famous, recorded in March 1971, was rejected by several record labels before being released on Sky's own label, Rainbow Collection, two years later.
