Buzzing with behind-the-scenes stories from Top 40 DJs - many just as popular as the records they spun - this lively blast from the past reflects the rhythmic pulse of Top 40 radio itself, where there was never a second of dead air. Anecdotal oral histories take you back to the rantings and ravings of dozens of "cooler rulers," like the Real Don Steele of "Boss Radio" fame, "fifth Beatle" Murray the K, WMCA Good Guy B. Mitch Reed, the colorful "Cousin Brucie," the inimitable Wolfman Jack, and the notorious Alan Freed. More than 130 photos put faces to the voices, while author Ben Fong-Torres guides you on a 40-year trek through radio stations all across the country - where Top 40 and a whole generation grew up.
