Question:
Art Bell III was born in Jacksonville, North Carolina, to Arthur Bell, Jr., a United States Marine Corps captain, and Jane Gumaer Bell, a Marine drill instructor. Arthur Bell, Jr. died in 2000, and Jane Bell died December 23, 2008. Bell has always been interested in radio, and at the age of 13 became a licensed amateur radio operator. Bell now holds an Amateur Extra Class license, which is in the top U.S. Federal Communications Commission license class.
Bell generally chooses not to discuss his political views on Coast to Coast AM, though occasionally he has brought them up. He has expressed support for the right to bear arms and same-sex marriage. He also used to be, in his own words, a "staunch" supporter of the death penalty, though he has changed his mind at least to some extent due to innocent people being sentenced to death.  Bell has at times seemed to support many different 9/11 conspiracy theories, such as the one that claims the World Trade Center was brought down by explosives planted in it in advance. However shortly after the September 11 attacks Bell uploaded an image stating "God Bless George W. Bush and the U.S.A." .  Bell is a member of the U.S. Libertarian Party. Originally, Coast to Coast AM was a conservative political talk show, but in recent years Bell has expressed both conservative and liberal views on the air. On air, Bell has shown support for immigration reform and decriminalizing marijuana. At other times he has expressed dismay at the presence of millions of illegal aliens in the US. He has at times criticized man's role in degrading the natural environment, while at other times he expressed doubt about the scientific basis behind human caused global warming. In fact hundreds of times he agreed with guests or callers who claimed global cooling was occurring or was about to occur. Bell has also stated that he opposes abortion. At the outset of the Iraq War in 2003 he stated he did not think that a war against Iraq was worth the life of "one American service man or woman." Bell supports a free market economy.  Bell supported Barack Obama for President of the United States in the 2008 election.

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.

Who replaced him?
He was replaced in the studio by current Skid Row bassist Rachel Bolan.
