29th August Show with Anthrax Cancelled

According to the Century Media, Lacuna Coil will not be supporting Anthrax on 29th August at the Trocadero, Philadelphia.
The Trocadero show schedule at www.thetroc.com shows only Anthrax with E.Town Concrete, though interestingly the Anthrax site states that the latter have dropped of Anthrax’s tour to join Ozzfest.

There doesn’t appear to be any official reason why Lacuna Coil have cancelled, so if anyone knows please let me know…
