Deletion of The Mistake (band)

Comment: I found http://www.metalunderground.com/news/details.cfm?newsid=25629 this article on Metal Underground.  I'm not 100% sure that's a reliable source, but I think I may cited that website before.  There were also a few trivial mentions scattered about – frankly, more than I expected – but not enough to establish notability to my satisfaction.  They released albums through Prime Directive Records, but I'm not convinced that satisfies  criterion #5.  If I'm wrong, ping me with some kind of evidence that it's an "important" label, whatever that means
