Here’s something different: a political feud that does not appear to have any connection to Donald Trump. The AP reports that a planned U.S. tour by Venezuelan-born classical music maestro Gustavo Dudamel has been canceled, apparently because Venezuelan President Nicolas Maduro has a beef with Dudamel.

The four-city tour, which was to feature Dudamel performing with the government-backed Venezuelan National Youth Orchestra, was spiked after Dudamel criticized the Venezuelan government’s crackdown on protesters. The tour, which had been scheduled to begin Sept. 9, was slated to hit the Washington area along with Chicago, Los Angeles and San Francisco.

“Dudamel on Twitter Monday called the cancellation ‘heartbreaking’ and said he would continue ‘to fight for a better Venezuela,'” the AP reports, adding: “Dudamel gave no reason for the cancellation, but Maduro last week blasted the Los Angeles Philharmonic’s musical director, accusing him of being duped by Venezuela’s enemies into criticizing the government that has for years been one of his biggest promoters.”
