Epitomizing the later, grittier face of Sunset Strip’s hair-metal heyday, L.A. Guns make an appropriate return to the club forever synonymous with that celebrated ’80s scene. Initially eschewing the poppier instincts and sugary production of many of their peers, the quintet instead spewed a snarky, bluesy take on post-Aerosmith sleaze rock that was equal parts overt energy and implied ill intent. Once again helmed by “classic lineup” frontman Phil Lewis and guitarist Tracii Guns — a Guns N’ Roses founder and namesake — L.A. Guns have kept the big-black-hair-and-leather-pants flag flying through countless incarnations (there were even two different, rival versions at times) to recapture the vital, visceral vibe of their first two, gold-certified albums. History, band members and venue combine to make this show the ultimate one-stop, double-shot Strip nostalgia trip.
