Metallica, the band known for its dark lyrics and heavy metal sound, is showing its soft side with the release of a children's book.

The "ABCs of Metallica" will include rhymes and illustrations that look back at the history of the iconic rock group, and all for a great cause.

A "portion of the proceeds" will benefit All Within My Hands "as we continue to support workforce education and the fight against hunger," the band's website states.

All Within My Hands was founded in 2017. The foundation supports workforce education, the fight against hunger and other critical local services.

The band worked with author Howie Abrams and musical artist Michael "Kaves" McLeer for the book's colorful illustrations, with the cover showing members Lars Ulrich, James Hetfield, Kirk Hammett and Robert Trujilloin in all their animated glory.

"Each letter of the alphabet highlights a moment along our journey from 'Garage Days' to 'Master of Puppets' to fun facts about us," the band writes on its website.

"ABCs of Metallica" hits shelves and online stores Nov. 26, 2019.
