Coven is an American rock band formed in Chicago the late 1960s. They had a top 40 hit in 1971 with the song "One Tin Soldier", the theme song of the movie Billy Jack. Coven was composed of vocalist Esther "Jinx" Dawson, bassist Greg "Oz" Osborne, guitarist Chris Neilsen, keyboardist Rick Durrett (later replaced by John Hobbs), and drummer Steve Ross. In addition to pioneering occult rock with lyrics and aesthetics that explicitly dealt in themes of Satanism and witchcraft, they are recognized by metal fans and metal historians as being the band that introduced the "Sign of the horns" to rock, metal and pop culture, as seen on their 1969 debut album release Witchcraft Destroys Minds & Reaps Souls. History Dawson and Osborne, after playing together in the group Him, Her and Them, formed Coven with Ross in Chicago in the late 1960s. In 1967 and 1968 they toured, playing concerts with artists including Jimmy Page's Yardbirds, the Alice Cooper band, and Vanilla Fudge. Coven signed with Mercury Records and released their debut album, Witchcraft Destroys Minds & Reaps Souls in 1969. The music on the album was considered underground rock; what made it distinctive was the heavy emphasis on diabolical subject matter, including songs such as "The White Witch of Rose Hall" (based on the story of Annie Palmer), "For Unlawful Carnal Knowledge", "Black Sabbath" and "Dignitaries of Hell". The album concluded with a 13-minute track of chanting and Satanic prayers called "Satanic Mass" (written by their producer, Bill Traut, of Dunwich Productions, and described as "the first Black Mass to be recorded, either in written words or in audio"). This Satanic Mass was also the first time Latin phrases such as "Ave Satanas" were used in occult rock music, and later Satanic and black metal bands continued this innovation (see List of songs with Latin lyrics for some examples). Also included inside the album was Coven's infamous Black Mass poster, showing members of the group displaying the sign of the horns as they prepared for a Satanic ritual over a nude Dawson lying on an altar. Unwanted publicity came to the band in the form of a sensationalistic Esquire magazine issue entitled "Evil Lurks in California" (Esquire, March 1970), which linked counterculture interest in the occult to Charles Manson and the Tate-La Bianca murders, while also mentioning the Witchcraft album and its Black Mass material.
