Event Announcement.

A vibrant social media event poster for a summer music festival, featuring a bold geometric sun bursting with rays in hot orange, magenta, and golden yellow. Silhouettes of festival-goers with raised hands dance along the bottom. The event name appears in chunky retro display font at center, with date and venue stacked below. Confetti particles and musical notes scatter across the design. The energy is celebratory and youthful, using a saturated tropical palette conveying outdoor summer vibes.
