According to a statement on Brook's website, the cancellation of all three shows happened "due to unexpected scheduling by the NHL and NBC on June 6 for the 2015 Stanley Cup Final."

The finals for the NHL's Stanley Cup are in full swing, and the Tampa Bay Lightning are scheduled to play the Chicago Blackhawks on Saturday, June 6, at Amalie Arena.

According to the Brooks' statement, they looked into moving the June 6 shows a day later to Sunday. Ultimately, however, they realized the turnaround time between events would lead to "safety concerns," and because of this, "the choice [was] made to refund all shows and reschedule depending on finding a date that works for both the arena and the tour."
