Eh, I don't know exact draw numbers, but I would've swore that both Whitechapel and Darkest Hour would draw bigger crowds than TBDM. Not that I'm begrudging their spot though - good for them if they really do pull those crowd numbers.
I don't really get Black Dahlia, but I understand and respect the huge influence they've had on a lot of bands I really like so I'm glad to see they're still going strong.
