The art style features rich, textured brushstrokes, grainy details, and a vintage retro aesthetic similar to gouache painting. Muted beige background with stylized shadows stretching below the musicians. Floating musical notes above. Color palette includes deep teals, warm oranges, purples, and earthy tones. Mid-century modern illustration style, flat design with rich textures.
