@marco1993, you don't need to translate festival names. But yeah, a Hungarian show would be awesome. (Or somewhere near us.)

The noticeable festivals in this region are the following:

• Nova Rock (Nickelsdorf, Austria; mid-June)
• Prague City Festival (Prague, Czech Republic; June 29, 2012)
• Volt Festival (Sopron, Hungary; end of June/beginning of July)
• Sziget Festival (Budapest, Hungary; early/mid-August)
• SZIN Festival (Szeged, Hungary; end of August)

I hope you can fit in the line-up of Prague City Festival, the main act's gonna be blink-182, Hey Monday would be my favourite opener for them. (And I've already got my ticket to that festival. )
