Mozart on the Street

I was diving into the flock of people on North Michigan Avenue yesterday in between my sessions (without breaking my shoes) when I found these guys; such an oasis in the afternoon where all I can find is the same old shops, similar as those on Fifth Avenue Manhattan, same as those on every American "mall"; the same coffee shop on every block (you know what they are...). I would only praise the clean street, beautiful trees and neat landscapes hiding on their shades, places for people to sit, and huge sidewalks enough for vendors and bikers and walkers (although almost no vendor I can find here...) and where fine music is performed, what else you could possibly asked for...
