The client has hired you to create a unique poster, paying homage to original jazz albums but creating something new out of it. They have approached you as they believe you can create this, but the actual poster is up to you.
The client has also asked for the creation of a hoodie and t-shirt design to sell at the event, to promote for future events and make the experience more memorable. The hoodie must have some connection or relevance to the poster design and contain references to jazz albums to create something new.
