well.. if you can take some holiday, i recommend the full moon festival in germany. it goes from friday to thursday (15.7. - 21.7.) and the line up is like a wet dream (at least for me..).
some of the artist:
atomic pulse, eskimo (weeeeeh), exaile, kindzadza, naked tourist, parasense (weeeeh²), sub6, star-x, talamasca, tristan, wrecked machines, xenomorph.. and may more.
