On this day in 1989, Mötley Crüe released Dr. Feelgood. The Crüe were already massive, but this was the record that took them to No. 1. Bob Rock gave the album an enormous, arena-level sound, the title track became the band’s highest-charting single, and Dr. Feelgood became Mötley Crüe’s first—and only—No. 1 album in America.
