Perpetual Conversion traces the career of bassist Dan Lilker from 1981, the year he co-founded Anthrax, through 2011, and details numerous influential bands he founded or joined, including the groundbreaking Stormtroopers of Death (S.O.D.), thrash legends Nuclear Assault, grindcore trailblazers Brutal Truth, and one of the earliest US black metal bands, Hemlock.
Although known among die-hard, underground metal fans, Lilker's influence has been significant across many genres. From his signature heavily distorted bass tone to his unquenchable thirst to create forward-thinking, aggressive music, Lilker's musical drive has seen him at the forefront of New York hardcore, crossover, thrash, grindcore, and black metal.
Perpetual Conversion is culled from extensive interviews conducted by author Dave Hofer with Lilker, his family, his peers, and his bandmates past and present, including personal accounts from Craig Setari of Sick of It All, Barney Greenway of Napalm Death, Dave Witte of Municipal Waste, Scott Ian of Anthrax, Gene Hoglan of Death/Dark Angel, Kevin Sharp of Brutal Truth, Digby Pearson of Earache Records, Fenriz of Darkthrone, Chris Reifert of Death/Autopsy, rapper Necro, Dave Mustaine of Megadeth, Jacob Bannon of Converge, and many others. In addition, the book is supplemented with excerpts from historic interviews, key reviews, and dozens of previously unseen images.
