As recently reported, a woman named Joice M. Figueiró gave birth to a baby boy at a Metallica show in Curitiba, Brazil, this past Saturday (May 7th). Now, the new mom has an even more legendary story to tell her son Luan when he grows up, as she and her husband received a congratulatory call from Metallica frontman James Hetfield.

Joice, a tattoo artist, attended the Metallica show while 39 weeks pregnant. She sat in the accessible seating section of the stadium, where she went into labor as Metallica started to perform “Enter Sandman.” With not enough time to get her to the hospital, she ended up giving birth at the venue’s outpatient clinic.
