Like many headliners getting ready to bring a new show to Atlantic City, Chris Botti is going to first carry out a long and time-honored tradition. He’s going to break the show in out-of-town, a common method — originated by Broadway producers more than a century ago — of testing the program out on an audience without having to worry about critics casting judgment before the show was ready for New York.

For his latest visit to Atlantic City, Botti, a jazz, pop and classical trumpet virtuoso and composer, took a few practice swings in Mexico at the end of August. Then it was off to Europe for shows in Latvia and Poland. And before returning to the United States to kick off his fall American tour with a Boardwalk gig, 9 p.m. Friday, Sept. 15, in Caesars Atlantic City’s Circus Maximus Theater, Botti was scheduled to play one final show.
