The band was loved by fans and hated by critics who were convinced they had ascended to fame based solely on hype. The quartet released IV in 1971 with only symbols to represent themselves in protest, and the determination that the music would speak for itself once and for all. They didn't even have to put their name on their fourth album and it became an all-time bestseller, going 23x Platinum in the U.S. without EVER hitting #1 on the charts.
