“The Kingdom” — a 60-date Yankee/Omar tour that is ­scheduled to run for two years. The partnership also includes a joint album and a TV show for the two artists, who between them have 11 No. 1 hits on Billboard’s Latin Albums chart, 28 top 10 hits on Hot Latin Songs, over 50 million followers on Facebook and Twitter alone, and have sold more than 5 million albums in the United States, according to Nielsen Music.

The tour is framed as a musical boxing match, with the two artists trading off musical sets or “rounds,” and with fans voting for their winner in each city through an app designed for the event. “Two kings, one throne,” says veteran concert ­promoter Raphy Pina, who took over Omar’s touring in 2013 and came up with the concept. Once he knew that both were interested in working together, getting the right concept was key.
