Jon Zazula

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.

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

The setlist centered on their Megaforce Records era.

It played on the screens before the concert.

Metallica have released the third and final live video from their recent celebration of Jonny and Marsha Zazula: "The Call of Ktulu."

The celebration of Jonny and Marsha Zazula continues as Metallica unveil another pro-shot video from their recent tribute show in Florida.

On Sunday, Nov. 6, Metallica stormed the stage at Hard Rock Live, a 7,000-seat theater in Hollywood, Fla., for an absolutely unforgettable night.

Taking it back!

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

See the reactions to the Megaforce Records founder's death on social media.

Rest in peace.

Metallica, Anthrax, Exodus and more have paid tribute to the influential Marsha Zazula.
