Every city has them and every tourist city has hundreds of them: buskers. When I studied in London I used to travel on the tube to university on the district line…there were a couple of guys who used to play and sing on the line from time to time and they were excellent.
Prague has some great buskers, some okay buskers and some that are just simply awful.
Here’s a video of a group of three musicians which I could have sat and watched for a very long time!
