Not that this would be the case here, but when HOB moved into New Orleans (with the help of the local gov't) the local folks got screwed. In particular, friends of mine who run a bar next door that used to sell food and have little bits of live music from time to time. HOB moved in with a restaurant and bigger shows and bunch of rules regarding what types of businesses could be in their area. No food, no music, no competition from neighbors.
I've only been to the HOB down there a few times and won't actually go back. I've only been to one 9:30 Club show that I thought was over sold, but the HOB shows are ridiculously oversold. Oversold like lift your feet and not only will you not fall, you'll move with the crowd. No HOB for me.
