When Lifetime played 930 last summer, the club took out the barrier and turned the place into an intimate club for the first time that I can remember. THey allowed stage diving, and the dance floor was huge, and the place was pretty packed. That was a great show. If I was seeing a mellow band, I would love to see them at the Black Cat; its a great venue with a great feel to it and from what I could tell, decent sound.
By the way. World Inferno was mind blowing. I can't remember hte last time I was that into an opening band. The friends I was with hated them; I couldn't have loved them more.
