For nearly 25 years, Greg Kot of the Chicago Tribune has been reviewing popular music: from indie up-and-comers and underground hip-hop artists to arena-filling rock-and-rollers and celebrity pop superstars. Turn It Up: A Guided Tour Through the Worlds of Pop, Rock, Rap and More is the first-ever collection of Kot’s Tribune articles, covering the years of 2000–2013. Kot delves deeply into the essential acts of the 21st century, the business of music as a whole, and the Chicago music scene in particular.
