Bold graphic poster for a fictional indie music festival "LOW TIDE SESSIONS 2026". A collage of black-and-white halftone portraits of young musicians — one with a guitar, one with headphones, one singing into a vintage microphone — cut into circles, arches and wave shapes. Mixed with flat cobalt-blue and tangerine-orange color blocks, thin sound-wave lines, small arrows and tiny lineup text set in a strict Swiss-style grid. A massive stacked headline "LOW TIDE" in heavy condensed type across the upper half, with "SESSIONS 2026" in a smaller weight. Off-white background, visible risograph grain and slight ink misregistration for a printed feel. Energetic but organized contemporary design. 4:5 vertical.
