Gray hair metal: Mötley Crüe, Def Leppard and Poison reenact the ’80s at SoFi Stadium

“Long way from the Sunset Strip,” Nikki Sixx said as he took in his surroundings, and that was certainly true enough: Instead of the Roxy or Gazzarri’s or one of the other sweaty West Hollywood nightclubs in which his band Mötley Crüe made its name, the 63-year-old bassist was peering out at the cavernous expanse of Inglewood’s gleaming SoFi Stadium, where Mötley Crüe touched down Saturday night for a hometown stop on the group’s latest tour. “This is exactly like the towel I gave your mom in 1987.” Constancy — and strength in numbers — is the concept behind the so-called Stadium Tour, which packages Mötley Crüe with two fellow survivors of ’80s pop metal, Def Leppard and Poison, as well as Joan Jett, who laid important groundwork in the mid-’70s for all the glammed-up guys to come. “Who likes the old s—?” Mötley Crüe’s frontman, Vince Neil, asked not long into the band’s set Saturday. Def Leppard was much tidier as it doled out the polished pop-metal hits that made the English band an early MTV sensation: Though Led Zeppelin’s Robert Plant recently made good-natured fun of frontman Joe Elliott’s elaborate vocal-warming routine, the precision with which Elliott hit the high notes in “Love Bites” and “Photograph” was indication that he knows what he’s doing.
