The last day of the United Islands festival is today, June 26th, 2011.
Line-up: http://www.unitedislands.cz/en/1081/2949.html
It's free. Although the afterparty is at Club Lavka, the lamest club in Europe, it looks like there's a variety of bands playing at the actual festival itself. Hoping for a good time.
The islands are located on the Vltava river.
