Walking through the streets of Prague it is easy to get a sense of culture and cultural traditions. It is not uncommon to see musicians wielding all manner of large, bulky instruments around the cobblestoned pavements of Stare Mesto. Instrument shops are here too. I haven't bought the red trumpet I saw. In fact there is a whole brass section in a rainbow of colours available for purchase, at the usual pricey prices of such things.
Theatre is alive here too. There is an upcoming Shakespeare festival (in Czech) although Jan tells me there are many small studio type perfomances here.
And for those with more "contemporary" preferences the Rolling Stones are playing Brno in July, Genesis is doing Prague in a week and what happened to that George Michael show I was considering buying a ticket for? Cancelled due to a problem with one of his trucks.
And if you don't like live performances, how about an exhibition or a museum. Plenty of offerings from cultural, to art, to decorative, to architecture, and at the moment in the Lucerna Arcade - "BODIES" - see http://www.bodiesprague.cz/ - no prizes for guessing that I am giving that one a big miss.
