These vibrantly colored posters are true masterpieces, combining psychedelic aesthetics with strong symbolic elements. They reflect the spirit of protest and experimentation of an era. Nowadays, graphic designers draw inspiration from this period while bringing a modern perspective to their work, demonstrating that this form of visual expression continues to evolve and resonate with our times. The exhibition will also spotlight equally design-led record sleeves that have helped, and continue to help, shape the visual identity of music groups. For the most part, they push the boundaries of graphic art. And some have become icons of musical graphic design. A true celebration of freedom of expression, more than 100 underground works produced from the 2000s onwards will be on show. These graphic artists, often on the bangs of the mainstream, have created works that defy norms and shake up expectations. While paying homage to their predecessors, whether Pop Art, the psychedelic forms of the 1960s or the punk style of the 1970s, the artworks on show reflect a constant desire for innovation. Visitors will discover striking posters, retro-futuristic album covers, bold illustrations and much more, all wrapped up in the rebellious spirit characteristic of underground graphic design. In addition, hundreds of alternative and underground publications from all over the world will be on display. Among them, American underground comics will be presented.
