Chris Brown & Trey Songz cancelled their Minneapolis concert because of low sales. They were only able to sell 3,500 seats out of 20,000 seats!!. Judging by the same low ticket sales in other cities he might be canceling more dates.
This is disappointing since we have like 3 artists headlining the tour (Chris, Trey, Tyga). August Alsina should be glad that he jumped ship and decided to open for Usher instead.
