Jon Zazula

Jonny Z wrote in his memoir, "I give God and my wife Marsha credit for every wonderful thing that has made this life so interesting."

On the latest edition of The Ultimate Metallica Show, we dedicated the first hour completely to the life and legacy of Jon "Jonny Z" Zazula.

On March 16, 1952, the world of metal changed forever. Jon Zazula was born in the Bronx and would grow up to co-found Megaforce Records with his wife, Marsha.

The band practiced at the house in the '80s.

The setlist centered on their Megaforce Records era.

Remember all the rock and metal musicians and icons who died this year.

On the heels of releasing the download of their old-school show in Florida, Metallica have unleashed a pro-shot video of their performance of "Phantom Lord."
