Not sure of the times but there were 3 guys playing them beautifully this morning and they look to be set up for the day. Looks like the "concert" is organised by one of the Zurich Churches, probably warming up for Ascension day tomorrow.

If you haven't heard these being played at close quarters, you're in for a treat!

Will you still be saying it's a treat after you have heard them 15 times over today?

I'm not working there today, but I doubt it'd be a problem, they were playing very gently and the horns were pointing in the direction of the tracks, away from the market. I'll be there from 5 though and will report back if they become a pain!
