A series of extremely simple, thin, continuous line drawings of a middle-aged Japanese man wearing a hat and playing an electric guitar (6-string jazz full-acoustic electric guitar). The man is sitting down, smoking a white cigarette. The posture is relaxed, with the head tilted slightly down and turned towards the guitar, expressing a deep concentration and melancholic atmosphere. The lines are drawn smoothly and elegantly, emphasizing the curves of the electric guitar and the gentle contours of the man's body. The overall atmosphere is one of quiet introspection and soulful expression through music.
