I chose this concert poster from The 1975. The hierarchy is clear to understand. The artists are ordered by size from headliner to opener. There is good white space between the concert title, the artists, and the concert information. The less important information is left outside of the main frame. Other than the band and concert logos everything is the same font, which is good for readability; the hierarchy is instead shown primarily through size and placement. Overall, I would say it is a successful tool for understanding the event.
