Nathalie, I have lived in Germany and speak German quite fluently (not perfectly but still quite fluently). I'd be happy to give the translation a try.
Can you try to get a copy of the magazine? Needless to say it won't be available here in Spain, which is a shame because reading in German is no problem for me. It's getting the magazine here that will be problematic.
As for that Palestinian band... I may be wrong, but isn't Acco in Israel proper rather than in the Palestinian territories? As I said I may be wrong but I thought it's somewhere in north Israel. Not too far from the West Bank but I thought it was in Israel proper. Not that it matters that much, the message of the band is clear. I'm quite confident Orphaned Land'd even be welcomed with open arms in Gaza. Their message of peace would probably be welcomed with a lot of positive responses from the population in the Palestinian territories.
