Part reference manual, part collector's guide, part critical overview, Wilcopedia is an insightful album-by-album, song-by-song guide to the music of the most important American rock band of the twenty-first century. It offers a thorough appraisal of the entire Wilco canon, with detailed insights into every album and song the band have released, as well as side projects, collaborations, covers, and more.

Since their formation in 1994, Wilco have become one of the most acclaimed and influential bands of modern times. While previous books have told their story in a biographical sense, Wilcopedia zeroes in on the music, tracing the evolution of the band's material from the studio to the concert stage, from the formative Uncle Tupelo recordings through the mold-breaking Yankee Hotel Foxtrot to latter-day gems Star Wars and Schmilco and beyond.

Throughout their twenty-five-year career, Wilco's founder and primary songwriter, Jeff Tweedy, has led his band through various shifts in line-up and genre that have kept fans on their toes and made their music difficult to categorize. While they are largely considered an Americana act, their music has touched on hard rock, electronica, pop, soul, punk, folk, and more—and Wilcopedia covers it all.
