Justin Bieber will soon be seen showing off his incredible vocal range at his 45 date tour beginning from May. The songwriter and singer is to go around North America for The Changes tour. However, it seems like Justin Bieber's show has not been able to do well at the ticket window so far. The Tour tickets have not been selling well and as per the American Airlines Center, his concert at AT&T Stadium on June 27 is being relocated to America Airlines Center on Sunday, June 28.
