In the smoke, Underground Jazz Club, A gray-haired one、Disheveled hair、Old hippie in a torn leather jacket plays the harmonica energetically, The air is filled with the soulful melodies of jazz. The bar is dimly lit, Retro posters and messy stage. The medium is a rough black and white sketch, Capturing the raw and authentic essence of a performance. The artistic style is reminiscent of urban street art, The lines are rough，Sharp contrast. The color palette is monochrome, Deep black and pure white accentuate the musician's rugged appearance. The lighting is dramatic, A spotlight illuminates the musician's expressive face and hands.
