Question: How many concert dates were in the 2 Worlds 2 Voices Tour? Passage 1:On March 2, 2012, Brown released the first episode of his Fortune web series, showing him backstage at the 2012 Lo Nuestro Awards where he performed "International Love" with Pitbull, playing in a celebrity basketball game during NBA All-Star Weekend in Orlando with rappers Common, 50 Cent, T.I., and singer R. Kelly, as well as partying and dancing at the club. In April 2012, Brown appeared in Australia as one of the performing acts for the urban music festival, Supafest. His set list composed of thirteen songs, which were "Turn Up the Music", "Till I Die", "Run It!", "Deuces", "Yeah 3x", "Look at Me Now", "Beautiful People", "She Ain't You", "Wet the Bed", "My Last", "Body 2 Body" and "Birthday Cake". On May 8, 2012, Brown appeared on Dancing with the Stars (US) to perform "Turn Up the Music". For the performance, Brown and his dancers wore suits. He later performed the song at the 2012 Billboard Music Awards, held at the MGM Grand Garden Arena in Paradise, Nevada on May 20, 2012. The performance featured projected images on the stage backdrop and BMX bike stunt troupes racing around the stage, as Brown performed choreographed routines while lip synching. His performance was met with a mixed response from celebrities, most notably Joe Jonas, Pink, and Carey Hart, who all criticized the singer for lip synching. On June 8, 2012, Brown appeared on NBC's Today show and performed "Turn Up the Music", "Don't Wake Me Up", "Yeah 3x" and "Forever", as part of the program's "Summer Concert Series". At the 2012 BET Awards on July 1, 2012, he performed a medley of "Turn Up the Music" and "Don't Wake Me Up", and appeared shirtless for the performance with half his body spray painted in grey. Brown performed acrobatic moves with six backup dancers "under triangle-shaped beams" as green and red flashing lights appeared throughout the stage.
Passage 2:Born in the Christchurch suburb of Fendalton on 19 October 1925, Gould came from a well-connected Canterbury family. His father was Derrick William Joseph Gould, a prominent businessman, racehorse owner and captain of the New Zealand polo team, and his mother was Elisabeth Mary Gould (nee Elworthy). His paternal grandfather was George Gould, whose father, also called George Gould, was one of the founders in 1851 of the financial agents Gould Beaumont and Company that in 1919 amalgamated with two other firms to become Pyne Gould Guinness, one of New Zealand's largest stock and station agents. Other notable relatives on his father's side of the family include his father's cousin, the historian George Macdonald, and former British Labour MP Bryan Gould, who is a descendant of the elder George Gould. David's mother was a granddaughter of both Churchill Julius, the first Anglican Archbishop of New Zealand, and Edward Elworthy, an important landowner in South Canterbury. She was thus a first cousin of Charles Elworthy, Baron Elworthy, and niece of Sir George Julius and Awdry Julius.
Passage 3:Clarkson has performed the song in eight of her concert tours. First, she performed the song on the Breakaway World Tour, Hazel Eyes Tour, and the Addicted Tour (200506). Later, Clarkson performed the track on the My December Tour (200708). She also performed the song on the 2 Worlds 2 Voices Tour (2008), a co-headlining concert tour with Reba McEntire. It was the first Clarkson song to be performed. Later, she performed the song on the All I Ever Wanted Tour (200910). On the Stronger Tour (2012), Clarkson performed the song as part of a medley, with "The Trouble With Love Is", "How I Feel" and "I Want You". When Clarkson performed the song on her most recent tour, the 12th Annual Honda Civic Tour, where she was a special guest for Maroon 5, she and her music director changed the arrangement to make it sound more jazzy. For her Piece by Piece Tour (2015) Clarkson mashes the song up with "Uptown Funk" by Mark Ronson and Bruno Mars.
