Prompt
Create an image of a middle-aged man with a gentle, introspective expression, sitting at a piano or surrounded by musical instruments, with a subtle background that hints at his American heritage and connection to the minimalist and post-minimalist music movements; he should be dressed in casual, yet elegant attire, reflecting his personality as a renowned composer; incorporate elements that nod to his notable works, such as operas or orchestral pieces, in a style that blends realism with a touch of creative expression, suitable for a portrait of John Adams, the celebrated American composer.
