For the rest of the poster I just went with the image. Helvetica is a more neat and modern typeface, so I decided to make the poster simpler, without too many other images or shapes. For grouping the information, the title should be the most important one, and reacting with the image. The subtitle could be in a more interesting shape and play with the image, but still readable. The second important thing on the poster should be the date, because when a person see a poster, once they saw the title and understand what the poster was about, they would look into dates first, then details about location and tickets. The details of location and tickets, I put them into the same weight. Both of them are the same importance.
