Perhaps oddly, there is a grain of truth here - but putting it at Studio seems to be a very, very unwise way of dealing with the truth (read on).
As you may know, disorder can be incredibly variable - one street safe, one street unsafe. Over the last 2-3 years, however, the "24/7 Scorpio" cluster on K Rd (just next to the bus bridge or whatever its called) - which is almost entirely hiphop/rap clubs - has exhibited an abnormally high degree of disorder and public place violence. So when Davison says "rap venues attract violence" he is telling the truth, because most of our rap venues are in that little cluster of K Rd.
However... I'd question the decison because
1) A KRS-ONE concert is very different to those clubs, and
2) Putting it at Studio is more likely to attract undesirables, fullstop.
Glad to be of help.
