Brad Parker was performing with his American disco group Generation Esmeralda in Brazil over the weekend when he suffered a sudden, fatal heart attack.
Caught on video, one can see the 59-year-old playing with the rest of the band before he collapses and fades from sight.
Somewhat behind the rest of his group, the band actually continues to play, clearly unaware of the emergency.
The New York Daily News has more:
Roadies and medics eventually rushed the stage and Parker was taken to a hospital, where he died on Sunday, a producer for the group told local media.
"Doctors performed all the emergency procedures but unfortunately there was no solution," Sergio Lopes said, according to Agence-France Presse.
Here is the video:
The group posted an announcement on its Facebook page, saying Brad died "doing what he loved best" and that the Brazilian government and local officials were exemplary in helping get the drummer home without delay.
The statement began:
To [dispel all] rumors and hopefully re-focus intentions to the family I am deeply saddened to report that during our concert in Uba Brazil last night, we lost our friend and brother Brad Parker to a fatal heart attack. Please [excuse] my feeble attempt to express our sadness over this tragic event. There simply are no words.
According to the New York Daily News the group was formed by former members of the band Santa Esmeralda, which was most popular in the 1970's.
