Cavalera Conspiracy’s show tonight at the House Of Blues in Hollywood has been thrown a curveball, as drummer Iggor Cavalera will no longer be able to sit behind the kit.  And why you may ask?  Iggor is trapped in London from flight delays caused by none other than the Royal Wedding.  William and Kate really should have considered Iggor while planning.

Fans don’t have to panic, though.  The show will still go on as planned, only now with Sacred Reich’s Greg Hall taking over the drums.  Apparently he had only 24 hours to prepare for the night’s show, but he still wants us to know that, “It will be fine.”

For those of you who can't make it out to tonight's show, you can still get your fill of Cavalera with the band's video below for "Killing Inside" off of their latest album, Blunt Force Trauma:
