IN: Francis Piol Bol Bok (born February 1979), a Dinka tribesman and native of South Sudan, was a slave for ten years but is now an abolitionist and author living in the United States. On May 15, 1986, he was captured and enslaved at the age of seven during an Arab militia raid on the village of Nyamlel in South Sudan during the Second Sudanese Civil War. Bok lived in bondage for ten years before escaping imprisonment in Kurdufan, Sudan, followed by a journey to the United States by way of Cairo, Egypt. Bok was aided by people of diverse cultures and faiths in his journey to freedom.

Seven-year-old Bok was captured by Giemma, a member of the slave hunting militia, who forced him to join a caravan of slaves, stolen produce, livestock and wares that the militia had captured in their raid of the Dinka settlement. When the members of the militia split up to return to their homes, Bok was taken by Giemma. Upon arriving at Giemma's residence, Francis was beaten by his captor's children with sticks and was called abeed. The word literally means "slave" and the stereotype is that of an inferior, demeaned, Negroid race. Francis was given quarters in a hovel near the pens of Giemma's livestock. Bok began a ten-year period of slavery at the hands of Giemma and his son Hamid. He was forced to tend the family's herds of livestock. He had to take them to pastures in the area and to local watering holes, where he saw other Dinka boys who were also forced to tend herds of livestock. He began to suspect that his life was going to change forever and that his father was not going to be able to save him. His attempts to speak to the other Dinka boys were futile, as they were speaking Arabic, which he could not understand; they also seemed afraid to speak to him. According to Bok, as he grew older, Giemma and Hamid began to place more trust in his abilities as a herdsman. Care of the cattle, horses and camels was passed to Bok and he was able to spend more time alone with the animals. Previously he had been under the careful supervision of Hamid and sometimes Giemma. In addition to having him serve as his slave, Giemma forced Francis to convert to Islam and to take the Arabic name of Abdul Rahman, meaning "servant of the compassionate one." In his autobiography, Francis states that although he was forced to convert to Islam, that he never stopped praying to God for strength to get him through his ordeal. Bok tried twice to flee from slavery at the age of 14. The first instance happened early one morning after he had been sent out with the cattle. Bok blindly ran down a road for several miles before he was captured by one of Giemma's fellow militia members. Giemma's peer returned Francis to the Giemma's compound, where he was beaten with a bullwhip. Bok attempted to escape once again just two days later, when he fled in the opposite direction of his previous escape. He once again fled for several miles, this time keeping to the forest. He stopped for water at a local stream crossing, where he was spotted by Giemma who happened to be there as well. Giemma forced Francis back to his home, this time promising to kill him. Francis was beaten again, but Giemma chose not to kill him, as Francis had become too valuable to the family as a slave.

IN: Stone Sour is an American rock band formed in Des Moines, Iowa, in 1992, performing for five years, before disbanding in 1997. They reunited in 2000 and since 2006, the group has consisted of Corey Taylor (lead vocals, guitar), Josh Rand (guitar) and Roy Mayorga (drums). Longtime members Joel Ekman (drums, percussion), Shawn Economaki (bass guitar), and Jim Root (guitar) left the group in 2006, 2011, and 2014 respectively. To date, Stone Sour have released six studio albums Stone Sour (2002); Come What(ever)

The band released a song called "The Pessimist" as a free download on their Facebook page on March 27, 2012. The song was previously only available on the iTunes deluxe version of the soundtrack to Transformers: Dark of the Moon. They also released their first DVD Live at Brighton in the same year, capturing their performance on November 7, 2010. It was announced via Instagram on May 3, 2012 that bassist Shawn Economaki had parted ways with the band on amicable terms. He was replaced in the studio by current Skid Row bassist Rachel Bolan. Stone Sour started recording their fourth studio album in early 2012. Corey Taylor stated that the album would end up being a double album or concept album, and described the album's sound as "Pink Floyd's The Wall meets Alice in Chains's Dirt". It was later announced that the new material would be released as two separate albums. The first album, House of Gold & Bones - Part 1 was released worldwide on October 23, 2012, and the second album House of Gold & Bones - Part 2 was released worldwide on April 9, 2013. The project also has a 4-part graphic novel series that accompanies the albums, telling the linear storyline featured in the twin albums' lyrics. The first two songs from Part 1, "Gone Sovereign" and the first official single, "Absolute Zero" were released for radio airplay in mid/late August 2012. The first single from House of Gold & Bones Part 2 was "Do Me a Favor". It was released digitally on February 12. Guitarist Josh Rand stated in an interview with O2 Academy that there was a song recorded for Part 1, an instrumental which was deemed 'not up to par' by the band. The song will likely be released in the future once James Root and Josh Rand do 'some stuff to it guitar-wise'. On October 5, 2012, Johny Chow of Fireball Ministry and Cavalera Conspiracy was announced as the bassist for the band on the House of Gold & Bones tour cycle. Stone Sour subsequently played Soundwave Festival 2013 in Australia and on the Sunday at Download Festival 2013. Guitarist James Root did not tour with Stone Sour in the winter of 2013, as he had to take a brief hiatus from the group to work on .5: The Gray Chapter with Slipknot, although it was later revealed that he was fired from the band due to musical differences. He claimed that the band wanted to focus on "radio play and money," in which Root fought against, and that led to a split. Christian Martucci filled in for Root during that period.
