Bob Rock's Three-Album Run That Rewired Hard Rock
Bob Rock produced The Cult's "Sonic Temple" at Little Mountain Sound Studios in Vancouver in 1988–89, then applied the same low-end philosophy to Mötley Crüe's "Dr. Feelgood" in the same room, before taking those instincts into the Metallica sessions at One on One Recording Studios in Los Angeles in 1990–91. The result was the Black Album, making Rock the production hinge between the stadium hard rock era and the heavier decade that followed.
