Chicago stands as one of America’s most successful rock bands of any epoch in terms of both sales and longevity. The statistics are simply staggering: over a forty-six-year recording career, the band has issued thirty-six albums, sold well over 100 million records, and released twenty Top 10 pop and twenty-two Top 10 adult contemporary singles (fifteen of which broke the Top 10 on both charts). It achieved the enviable feat of placing these hits on the Billboard charts in five different decades. Seventeen of their first twenty albums were certified platinum, nine of those multiplatinum, and Chicago 17 (1984) hit platinum a whopping six times.
