Another BOK Center Act To Be Announced

Friday brings a vaguely worded announcement and stirs speculation about the next big act headed to Tulsa's BOK Center.

The city says it has a "monumental" act on deck, and it's even surprised the promoter could convince the act to come to Tulsa.

The promoter is Live Nation which represents U2, Jay-Z, and Madonna.  Madonna is touring this fall, and has four open dates between her concerts in Denver and Houston.

The city won't announce who's coming to town until Tuesday.
