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.

Katrina Kaif (pronounced [k@'tri:na: 'ke:f], born Katrina Turquotte, 16 July 1983) is an English actress who works in Hindi films. Despite receiving mixed reviews from critics for her acting prowess, she has established herself in Bollywood, and is considered among the country's most attractive and highest-paid actresses. Born in Hong Kong, Kaif and her family lived in several countries before she moved to London. She received her first modelling assignment as a teenager and later pursued a career as a fashion model.
Katrina Kaif was born in Hong Kong with her mother's surname Turquotte (also spelt Turcotte), on 16 July 1983. According to the actress, her father (Mohammed Kaif) is a British businessman of Kashmiri Indian descent and her mother (Suzanne, also spelt Susanna) is an English lawyer and charity worker. She has seven siblings: three elder sisters (Stephanie, Christine, and Natasha), three younger sisters (Melissa, Sonia, and Isabel) and an elder brother, Michael. Isabelle Kaif is also a model and actress. Kaif's parents divorced when she was a child, and her father moved to the United States. She said her father had no influence on Kaif or her siblings while they were growing up, and they were raised by their mother. On her father's absence in her life, Kaif stated: "When I see friends who have wonderful fathers who are like pillars of support for their families, I say, if only I had that. But instead of complaining, I should be grateful for all the other things I have". In a 2009 interview with The Indian Express, she said she was not in touch with her father. Kaif says that her mother decided to "dedicate her life to social causes", which led to the family's relocation to a number of countries for varying lengths of time: Our transitions in growing up were--from Hong Kong where I was born, to China, then to Japan, and from Japan by boat to France ... After France, Switzerland--and I'm cutting out many East European countries where we were for only a few months each--then Poland in Krakow ... After that we went to Belgium, then to Hawaii, which was a short time, and then came to London. Due to their frequent relocation, Kaif and her siblings were home-schooled by a series of tutors. Although she is thought to have grown up in London, she lived there for only three years before moving to India. According to Kaif, she then changed her surname to her father's because she thought it would be easier to pronounce. Kaif's paternal parentage has been questioned by some members of the film industry. In a 2011 interview with Mumbai Mirror, Boom producer Ayesha Shroff accused Kaif of fabricating her history: "We created an identity for her. She was this pretty young English girl, and we gave her the Kashmiri father and thought of calling her Katrina Kazi. We thought we'd give her some kind of Indian ancestry, to connect with the audience ... But then we thought that Kazi sounded too ... religious? ... Mohammad Kaif was at the top, and so we said, Katrina Kaif sounds really great". Kaif called Shroff's comments "hurtful".
