Kissogramm really rocked, too, a surprise as well. For some reason I mixed them up and I thought they were something electronic. But it was actually fun indie rock, a nice surprise. I like electro, but I'm really a bit tired of it - now that even Spiegel Online has a electro column, it will probably be dead soon.
Of course, these weren't the only bands. There were also Art Brut, September Leaves, Sugarplum Fairy etc.etc., all that little Indie rock stuff plus some good parties after that. Nice one, little PopUp. Much more like a family meeting than Popkomm.
