A Brazilian music producer who was a leading nominee at the Latin Grammy Awards was killed in a motorcycle crash in Los Angeles early Thursday, hours after leaving the show, police and his record label said.

Tom Capone, who was nominated for five Latin Grammys and produced award-winning albums by Brazilian singer Maria Rita and the rock band Skank, died from massive head trauma after his rented Harley-Davidson collided with a car.

Capone was driving down Ventura Boulevard when his motorcycle and a Dodge Neon driven by a 23-year-old woman smashed into each other at an intersection, Los Angeles Police Lt. Steven Allen told Reuters.

The 37-year-old producer was wearing a "novelty helmet" that would not have provided much head protection, Allen said.

Capone, whose real name was Luis Antonio Ferreira Goncalves, was pronounced dead at the scene.

Allen said Capone may have run a red light and that the woman, who was not injured in the crash, passed a sobriety test and would not be charged.

"Somebody ran a red light," he said. "The only person still alive says she didn't run a red light."

A spokesman for Warner Bros. Music Brasil confirmed that Capone was killed in a motorcycle accident.

While little known in the United States, Capone had gained fame in the Latin American world, and Billboard magazine reported that with his five Grammy nominations he became the most nominated Brazilian ever.

Capone was nominated for album of the year and best engineered album for "Maria Rita" and for producer of the year. He was also nominated twice for record of the year, for Maria Rita's "A Festa" and Skank's "Dois Rios."
