German website
Rockpalast.de will be covering the Rock Am Ring festival, including Iron Maiden's set, this Friday.
Along with various reports and photos, this includes a live stream, which will be available
here on the day (you'll need RealPlayer to listen).
Iron Maiden take to the stage at 10pm local time, so that's 9pm in the UK.
This might be useful if you're trying to work out the timezones!
And if you live in Germany, you're really lucky - highlights from Rock Am Ring will be shown on WDR tonight.
