In 2004 — 50 years after Elvis Presley walked into Sun Studios and cut "That's All Right" — Rolling Stone celebrated rock & roll's first half-century in grand style, assembling a panel of 55 top musicians, writers and industry executives (everyone from Keith Richards to ?uestlove of the Roots) and asking them to pick the most influential artists of the rock & roll era. The resulting list of 100 artists, published in two issues of Rolling Stone in 2004 and 2005, and updated in 2011, is a broad survey of rock history, spanning Sixties heroes (the Beatles) and modern insurgents (Eminem), and touching on early pioneers (Chuck Berry) and the bluesmen who made it all possible (Howlin' Wolf).

The essays on these top 100 artists are by their peers: singers, producers and musicians. In these fan testimonials, indie rockers pay tribute to world-beating rappers (Vampire Weekend's Ezra Koenig on Jay-Z), young pop stars honor stylistic godmothers (Britney Spears on Madonna) and Billy Joel admits that Elton John "kicks my ass on piano." Rock & roll is now a music with a rich past. But at its best, it is still the sound of forward motion. As you read this book, remember: This is what we have to live up to.
