I can't comment on the artist pay stuff, but the rest of the article doesn't ring true to me. I think the Black Cat has been getting better - i.e., there isn't an interminable line for every sold out show.
And how can the author rag on the club for banning BJM when the R'nR Hotel claims to have banned two dozen bands in the year or so they have been open?
The article just sounds like sour grapes.
