J Balvin held a seven-hour concert in Medellín, Colombia, that was so physically taxing that it led to a medical emergency for the Latin reggaeton artist.
Just weeks after the gig, the Rayo artist sat down with streamer Ibai and shared that he was "still recovering" from the seven-hour performance.
"Normally, we go through moments as artists where you want to do concerts for your ego, but in this case, I focused on giving the people a show," Balvin said in Spanish in the video below.
While guests like Ryan Castro and Maluma were there to support Balvin, the artist shared that one intense moment of the night nearly cause him to stop the performance.
"At one point [of] the concert, I started to feel like I couldn't see anymore," he said. "I mean, you're in the middle of a 360 stage and I was only seeing everything as black and I was talking through the intercom."
"The people outside can't hear you, but your work team can hear you," he continued. "So I was like, 'Hey, I'm getting dizzy. I can't see. I'm pale.' And there was a moment when, while I was singing, I put my hand on my face. I was completely frozen.
"So, when Yandel came on [stage], I came off. The doctor took my pulse, it was 190 beats per minute, I mean, I was on the verge of a heart attack."
While the doctors examined Balvin, his mother was also there to comfort him, and the singer said she was "emotional."
"She said, 'My son, you have to stop the concert, you're not going to die here,'" the artist recalled.
To keep himself leveled, Balvin said he ate six frozen desserts, which caused an insulin spike.
"I still can't get over it, to be honest," he said.
Despite Balvin's health scare during the concert, his performance was a benefit to the Medellín and revitalized the city's tourism.
