While being well-known for heavier hits like "Master of Puppets" and "Enter Sandman," there's no denying Metallica's members have talent, even if that's not your style of music. James Hetfield, the lead singer, was pretty generous with his talent when passing it onto his daughter, Cali, who clearly has a knack for music, heavy or not.
During Hetfield's headlining set at "Acoustic-4-A-Cure" which benefits the Pediatric Cancer Program at UCSF Benioff Children’s Hospital, he brought Cali out for a father-daughter duo. Hetfield completely changed up the genre he normally plays and instead he played Adele's "Crazy for You" while Cali sang, showing off that AMAZING voice she has. Hetfield couldn't keep from making his heavy metal faces, but damn that girl can sing.
I can't lie to you, I've never even heard that Adele song and I'm at a loss for words.
