A poster / playbill design for a live music night

I am looking for a talented designer to create a poster/playbill design for a live music night with a retro theme. The design should incorporate abstract art elements and be colorful. The design will also need to incorporate text elements that convey details of the event.

Skills and experience required:
- Strong graphic design skills
- Experience in creating posters or playbill designs
- Proficiency in using design software
- Creativity and ability to incorporate retro and abstract art elements into the design
- Understanding of color theory and ability to create a vibrant and eye-catching design
- Ability to create a caricature and other cartoon like elements

Title: It's downhill from here
Sub-Title: The downhill side of hump day
Featuring: Colby Miller

Additional details will be provided. Wanting to visualize the 'downhill' element. I'm thinking a caricature of myself driving a truck with guitars in the back of the truck headed down a hill.

The ideal candidate should be able to effectively capture the retro theme and create a visually appealing design that grabs the attention of the audience.

I will provide some source 'inspiration board' material attached
