Taking a break from the sex, drugs, and rock ‘n’ roll, Motorhead and Judas Priest are slowing things down a little, as the iconic rock bands move into the serenity of the adult colouring book trend.

In a new deal brokered by Global Merchandising Services, the two groups have partnered with Rock N’ Roll Colouring to launch the first, officially endorsed colouring books, featuring iconic artwork from classic albums.

‘Each book allows you to raise the horns in celebration of two of Heavy Metal’s most legendary and important bands, letting your imagination run riot as you create your own personalised versions of your favourite designs,’ read a statement from the firm.

Each book in the series contains renderings of each image, with detailed outlines for fans to unleash their artistic skills using pens, pencils, or paint.

Rock N’ Roll fans was devised and created by two life long rock and heavy metal devotees and colouring book fans.

‘Every effort has gone into making sure these books do justice to the legacy of both Motorhead and Judas Priest, and gives fans another reason to enjoy some of the most beautiful and creative artwork from these bands,’ said the company.

‘Not only that, colouring has proven significant mental health benefits including mindfulness, relaxation, and increased focus, and can be enjoyed by any age group. These two books provide hours of creative and restful activity that combines a love of the music with a love of the art,’ it added.

Both books will be published on November 2 this year and will be available for worldwide shipping.
