Guns N' Roses Arrive at Troubadour! Well, Most of Them

Guns N' Roses just started arriving at the famed Troubadour in West Hollywood for Friday night's epic show ... and they look like they mean business.

We got video of Slash, Duff McKagan, Richard Fortus, and Dizzy Reed as they showed up at the Troubadour to a throng of screaming fans. The guys didn't sign autographs or pose for pics. Pretty clear they're focused on the concert.

No sign of Axl Rose, but it's possible he arrived way earlier than the rest of the band.

Hahahaha!!!

Seriously though ... check out this shot of the Troubador stage. This is really freakin' going down!
