When Christian rock band Skillet revealed their “Kingdom Of Rock” book, their fans were taken aback. Exclusive bundles can only be pre-ordered through midnight CT on November 21 using the Skillet app with the code “Allthatmatters.” Additionally, there is an early Black Friday deal of 20% off all book packages. The book will be accessible on Skillet’s online store after the pre-sale. Because they blurred the boundaries between popular rock and Christian music, were “too spiritual,” “too positive,” and featured female musicians—almost unheard of in rock ‘n’ roll—many individuals in the music industry predicted that Skillet would never succeed. After 28 years and 22 million record sales, Skillet is still defying expectations. The band has sold out arenas in 32 countries on five continents, including the Middle East, where they recently completed their first-ever tour that was almost entirely sold out. Brands like WWE, Marvel, ESPN, NFL, “Conan,” USA Today, and The New York Times have highlighted Skillet’s unapologetic messages of hope and forgiveness thanks to their big hits, including the five-times-platinum “Monster” and the two-times-platinum “Feel Invincible,” which peaked at the top of rock radio.
