Hot Topic = hardcore??

FULL DISCLOSURE: I like Hot Topic, and I buy things from them from time to time.

Can a band really be "underground" when Hot Topic is presenting it? Apparently, the House of Blues in Orlando thinks so. When I opened the email from them yesterday, this is what I read:

Hot Topic Presents Sounds of the Underground with GWAR and Chimaira, Every Time I Die, Job For a Cowboy, Necro, Darkest Hour, Amon Amarth, The Acacia Strain, The Devil Wears Prada, HeavyHeavyHeavyLowLow, The Number Twelve Looks Like You, Goatwhore, This Is Hell, 2 Cents***This Show is at UCF Arena***

I'm sure I know several people who will be going to the show. (FYI, Goatwhore is terrible. I saw them a few years ago, possibly with Pantera, but I wouldn't swear to it.) I wonder if they feel that GWAR and Chimaira have sold out. How much can one accept from the corporate gods before the soul shrivels and the hardcore balls shrink? For that matter - is it "selling out" to market your 12" at Hot Topic? Or just a canny use of "the man" to reach hitherto un-evangelized masses?

I think the real, ultimate, burning question is this - can you be hardcore if you buy your concert-gear and records at a mall? Discuss.
