Henrique was performing in Feira de Santana, Bahia, at a private event for influencer Lôise Abreu.
The event was also broadcast live on social media platforms.
In the startling clip, Henrique is standing at the edge of the stage, urging the crowd to sing along as he holds his microphone out before he seemingly loses his balance and falls over in front of his band.
His record label, Todah Music, said he was pronounced dead at a local medical clinic and suffered a massive heart attack, according to TMZ.
The Post has contacted reps for Henrique for comment.
“There are very difficult situations in life for which we have no explanation,” the label said in an Instagram statement Thursday, translated from Portuguese. “We just need to understand that God’s will prevails! Pedro was a happy young man, a friend to all. An only son. A present husband and a super dedicated father. The Christian music sector is in mourning. The Todah Music family is in mourning. Heaven in chorus welcomes an illustrious son: Pedro Henrique! So long, dear brother! So long! May the Holy Spirit comfort everyone.”
Henrique is survived by his wife, Suilan Barreto, and his 2-month-old daughter, Zoe.
His wake and funeral will be held in Porto Seguro, Bahia, where Henrique was born, his team told Billboard Brasil.
Henrique’s single “Medley: Levanta / Não Fica Assim / Descendência (Ao Vivo)” was released on Thursday.
