Concert Announcement.

A psychedelic rock concert poster inspired by the San Francisco poster art of the late 1960s. Swirling, organic lettering morphs and flows like melting wax, spelling out the band name in nearly illegible but visually stunning typography. The background features kaleidoscopic patterns of electric purple, acid green, hot pink, and sunshine yellow radiating from a central mandala. A stylized figure plays guitar surrounded by blooming flowers and cosmic starbursts. The ink appears to have been screen-printed with slight registration misalignment, adding authentic vintage charm. Every inch of the poster is filled with intricate decorative detail.
