group of men in what appears to be a tent-like structure

group of men in what appears to be a tent-like structure. Four men are seated at the front, wearing white shirts and singing into microphones. One man is seated directly in front of the camera, and another man is standing behind him. The man standing is wearing a dark vest over his white shirt, and is holding what appears to be a brass instrument. Behind them, several other men are seated around tables, observing. There are bottles of water and fruit on the tables. The background of the tent is made of striped fabric. The overall setting suggests a gathering or performance, possibly of a musical nature.
