I was talking to Adrian, the lead singer of Smash-Up Derby, and it turns out that he's a big fan of E40 (who you were previously mentioning as a possible headliner for your next event in Las Vegas).
You know me, I still think Dave Navarro or Tommy Lee are good picks too, since they have both rock and porn credentials, but I'm sure it will be cool with whomever you select.
BTW, I felt that the DJ sounds at Rock the Ball in San Francisco meshed perfectly with the live band, so a mixed Ball might be good - a little something for everybody.
This already has the makings of another D-Money legendary Las Vegas adult industry party...
