marching band parading down a city street lined with tall apartment buildings. The band members are dressed in black uniforms with red and white trim, and most are playing trumpets. They are marching in neat rows, following a flag bearer at the front of the formation. A young boy in a matching uniform walks alongside the band's lead. There are a few onlookers on the sidewalk, observing the procession. The day appears sunny with a clear blue sky.
