Part reference book, part history, and part road map to the connectivity of popular music, this book is a must for all rock ‘n’ roll fans as it brings together a compilation of over two hundred genres of rock music—an entertaining, enlightening, knotty family tree of America’s favorite musical genre.In the six decades since rock ’n’ roll stole America’s soul, the single genre has produced over two hundred sub-genres. The days of being able to walk in to a Tower Records and seek out recommendations from an aloof, all-knowing staffer has been relegated to a long-lost Generation X paradise preserved in John Hughes films. From iTunes to Spotify, listeners now regularly turn to algorithms instead of human advice to develop relationships with the music they love.The essential companion for any rock lover’s collection—be it on vinyl or Spotify playlists—Appetite for Definition breaks down algorithms into their human stories and interconnected histories.  It provides and pulls up recommendations from a deeper well of consideration and gives you the tools to do the same. Operating on a macro level it surveys the myriad microlevel movements into an accessible map that readers can use to navigate the vast, craggy terrain of rock music and take their rock knowledge—whether casual or obsessive—to the next level.
