"This is a song that's not dedicated to drinking or drug addiction or of any of that kind of stuff. This song's basically about a walk in the park." As good an intro as any for GnR's livewire performance of Appetite for Destruction highlight "Nightrain," filmed for MTV's Live at the Ritz concert series at the peak of the band's powers in 1988. They crackle with as much urgency and menace as they ever did, and no matter how many times you watch it, Axl's stealth costume change (from shirtless gutter rat to West Coast Rob Halford) still comes as a hilarious surprise.
