Despite having a successful comeback album last year with ‘The Emancipation of Mimi’, Mariah Carey’s ‘The Adventures of Mimi: The Voice, The Hits, The Tour’ is having a hard time selling tickets. According to MariahCarey.com, three shows (September 3 in Hershey Pennsylvania, September 18 in Denver Colorado, September 25 in Seattle Washington) have just been canceled. Tickets for her tour went on sale nearly a month ago and NONE of the shows have sold out yet. A huge pool of tickets are available for every Mariah show currently listed on ticketmaster.com. Even the very cheap $18 tickets are still widely available for her concerts. Where have the Mariah fans who massively bought her album have gone since last year? If these shows are unable to combat low sales, more cancellations are likely.
