This design is a poster for a concert. It is simple and grayscale with flat illustrations. But it is creative and fun. The large amount of negative space is well planned. It looks like it was a fun poster to design.
I like the white keyboards in the shape of building structures and one of the black keyboards is a human form. The illustrations definitely tell a great story that match the theme.
