American folksinger and songwriter Patrick Sky established himself in the mid-1960s as one of the most enigmatic performers of the Greenwich Village folk scene. Beginning with traditional folk songs, he later became known for his biting political satire; his most confrontational album, Songs That Made America Famous, was rejected by several record labels before finding release on Adelphi Records in 1973. Of Creek Indian and Irish ancestry, Sky shifted toward Celtic music in the latter half of his career. He was one of the founders of the Green Linnet label and became known as a master of the Irish Uilleann pipes. Sky died of cancer in May 2021.
