This document discusses visual design principles for concert posters. It analyzes posters for three musical acts: Slipknot, Tom Odell, and Florence + the Machine. For each poster, the most important information like the artist's name is placed in the top line of sight in large, bold text to immediately catch the viewer's attention. The artist's photo is prominently featured in the primary focal area. Less important details are placed in smaller print near the bottom to direct the viewer's eyes while still conveying relevant information. The document examines how these posters effectively employ lines of sight and optical hierarchy to introduce the artist and engage the audience.
