Well... Get yer popcorn:
About a year ago we were meant to be playing a show in Greece, we arrived at the venue, set up, finished the soundcheck, everything was fine and just a couple of minutes before the first act jumped on stage, the venue got attacked by some obscure paramilitary outfit, armored with helmets and padded biker suits (around 30-35 of them), using stun grenades, petrol bombs and crow bars. The FOH/PA guy as well as most of the people running the venue were hospitalised with broken legs and arms and split heads. They stole merch and money, damaged the backline, stole some of the band's equipment, trashed the venue, and left again.
We then realised (after being told by people standing outside) that riot cops had surrounded the area about an hour before the attack, and basically let these guys through to wreak havoc, while not allowing anyone to leave the area during the attack. The attackers then somehow disappeared without any police interference. We packed what was left of our equipment and for about an hour or so could not leave the area because of the riot cops. Eventually we managed to get out of there. Greece is ****ed. The civil war there has been getting worse and worse for the past couple of years, and although it is not officially declared and not reported on the mainstream media, the localised armed conflicts can get pretty bad, faster than you can realise. It is easy to get caught in the middle of something.
That, and another time when we didn't even manage to make it to a venue, again on tour, this time in Austria.. We were scheduled to play in Vienna, but while entering Austria we were detained at the border for no apparent reason. About an hour later, a border cop informed us that he wants money from us. We ask why, and he tries to tell us it is a fine.. We refuse to pay unless we see paperwork, so he lowers the price.. We still refuse to pay, so he lowers the price even more.. We still refuse to pay and he threatens us with jail time. We call our embassies and they say they will look into it. The cops then proceed to deport us from the country before the embassies could call back. After being deported, we contacted our embassies again who said there's not much they can do about it, Austria refuses to cooperate.. We were told we're lucky to get away from this situation with almost no loss, because the week before they confiscated an entire vehicle with its contents because the driver refused to bribe them...!
So, my problems have much less to do with digital interfaces misbehaving.. My problem is more with corrupt governments, rogue nations, and bad luck.
I have since toured Greece again with no problems. I have never and will never go back to Austria, since I found out I need to appoint an Austrian lawyer to represent me in court to challenge the deportation, to be allowed to enter the country.
By the way, I do not use anything with a digital or computerised interface when performing live. This has solved plenty of my problems with such things. I always carry a soldering iron and some parts.. So all PA and backline issues are promptly resolved at soundcheck...
Fixing things smashed with crowbars, or petrol-bombed, on the other hand, proves to be a bit more challenging... The worst part, however, as mentioned before in this thread, is the human losses, even if it's injuries and not death.
