Carin León gave a brief but magical show on Tuesday night (November 14) during Latin Grammy week at the Amazon event “La Cultura that Connects Us” in Seville, Spain. The Mexican music star surprised his fans with a series of duets that included Spanish singer Omar Montes, Puerto Rican singer-songwriter Kany García and Mexican icon Pepe Aguilar, in an apparently improvised moment.

With the former, he performed his new collaboration “Ron con Coca,” released exclusively through Amazon Music earlier this month and which combines traditional sounds from both countries. “Up with Spanish music!” said León when inviting Montes to join him onstage, with the Spaniard artist adding that he somewhat nervous because it was the first time they were performing it live.

A bit later, he called García to sing their July-released collab “Te Lo Agradezco,” with both showing off their great vocal prowess. But one of the biggest surprises was Aguilar, who was enjoying the show with his daughter, singer Ángela Aguilar, in the front row and their preseence did not go unnoticed by León.

“As maestro Pepe Aguilar taught me,” León said after reaching hight notes with impressive power, immediately inviting him to come up and sing something with him. “And what are we going to sing, güey? No manches!” Aguilar told him once onstage. After a quick exchange, they decided on José Alfredo Jiménez’s classic “Te Solté la Rienda,” creating beautiful harmonies on the spot.

Held outdoors at the emblematic Setas de Sevilla — an imposing white pergola-shaped structure located in the central Plaza de la Encarnación — the show began with a performance by Spanish singer María José Llergo, who also impressed with her combination of flamenco and pop.

Latin Grammy Week ends on Thursday (Nov. 16) with the annual awards ceremony, which will be held for the first time outside the United States, at the Conference and Exhibition Centre in Seville. The show will air starting at 8 p.m. ET on Univision, UniMás and Galavisión in the U.S., and at 10:30 p.m. CET on Radiotelevisión Española (RTVE) in Spain.
