Hollywood Vampires Draws HUGE Rock Star Crowd (VIDEO)

It was like an awesome Sunset Strip flashback .... enormous rock stars and lots of 'em showed to watch Johnny Depp's band, Hollywood Vampires, perform at The Roxy.

Check out the video ... in order you see Johnny, Kesha, Tom Morello, Matt Sorum, Vince Neil, Tommy Henriksen, Perry Farrell, Amber Heard, Alice Cooper, Joe Perry and Paul Stanley.

And then there's "NCIS" star Pauley Perrette ... beside herself with excitement -- and possibly vodka -- as she left the club.  Love her.

Aren't you sad you missed it?
