Poster Designs

Been looking at a variety of posters, unfortunately couldn't find sources either but the way they both deal with the content is something I need to reflect in my own work. The imagery is all relevant and well processed, the text is fitting with the subject matter and the minimal, yet busy layouts create some unique compositions. Also the visuals created through just sound, shape and a general experimentation with cymatics is clean and well communicating of the content, again I need to decide on the most appropriate - typeface, stock, binding methods etc
