My wife and I were in Prague last Sept. - a beautiful city and quite walkable (also good public transportation). Stopped by a restaurant courtyard just off the Old Town Square, where a small group was playing trad music with dancers (I think it was more Romanian gypsy than Czech). At the east entrance to the Castle (Hradcanske namesti) there is a fine string-quartet street music group playing trad Czech music - say hello to Josef (with the mustach). Re the cymbolon - when we were in Dresden earlier, along the river, stopped to hear and talk to two street musicians - father playing a flute accomp by his son on the cymbolon, probably Rom gypsies, not German. Enjoy your trip - Prague is beautiful.
