A live jazz performance is underway at a dimly lit venue

A live jazz performance is underway at a dimly lit venue. On a small stage, a quartet of musicians is performing. A drummer wearing a hat sits behind his kit, while a man in a suit stands at the center playing the saxophone. A musician plays the upright bass and another performs on the keyboard. The stage is set against a red velvet curtain, illuminated by overhead spotlights. An audience watches the show from below, the backs of their heads and shoulders visible in the foreground. The overall ambiance of the venue is intimate and subdued.
