--And I think Glenn mentioned they'd trashed a hotel room or a backstage room or something, which qualifies as 'unprofessional.'[/QUOTE
It's true.. they destroyed both, hotel room and backstage room
The reason?.. they wanted to play 10 minutes more than the signed in contract , the promoter couldn't modify the schedule, because after Mago de Oz followed to play Danzig and Motorhead.
This happened during MMF Vol. II here in Monterrey Mexico, May 2005
(MMF = Monterrey Metal Fest)
Six months later, the band played here again (november 2005) and Txus, the drummer and leader of Mago de Oz offered apologizes and he said that the band had to pay $60,000 USD for damages.
