Two videos of Bohemian Bards playing at Staroměstské Náměstí (Old Town Square) in Prague. My videos are not very good, but these guys are great musicians!
Also, I don't think I've posted a video of the famous Astronomical Clock of Prague going off, which it does every hour during the day. Thousands of people gather to watch it. It's not the most exciting show, but it's pretty cool that it's been happening for about 600 years. It's hard to see unless you maximize the video: there are four figures that move, two on each side of the astronomical clock, that represent Vanity, Greed, Death, and Pleasure. Death, the skeleton, rings a bell throughout. Above the clock, the two windows open and the Twelves Apostles parade by. At the very end, the rooster (above and between the two windows) crows, and it's kind of a hilarious sound, like he's about to die.
The round dial below the astronomical clock is a calendar with all the Czech name days listed, one for each day of the year. The clock that actually shows the time is way up on the tower. You can see it in this video of an awesome light show done in 2010 that commemorated the clock's 600th birthday.
