The sidewalk is not a concert hall. But the street musicians are there. Their army is small. Their faces are familiar, but their names are unknown. The street musicians do what nobody else does – they scatter colors in the gray everyday life. They offer us with forgotten sensations, lost memories. Sometimes they grant us with a spare tear, that we wipe secretly. They turn the city into a place for living. Sometimes we drop a coin in the cases of their instruments. But is their deed worth just a coin – they turn the sidewalks into concert halls, and us – into humans. The street musicians are our guardian angels. This film is a tribute for them.
