With this in mind I thought about including an image of the cathedral as it's such a unique venue for a rock show so it made for a rather extraordinary gig. I hit on the idea of a grizzly bear climbing the cathedral tower King-Kong style fairly early on but it proved a bit too tricky so I settled for him grabbing onto one of the spires instead. Either way I'm quite happy with the results.
To create the image I used a similar technique to the Yeah Yeah Yeahs poster by using the pen tool in Illustrator to create shapes and build up each component of the poster. I quickly mocked up what I wanted on Photoshop and kept a jpeg in the background as a guideline of where things went in relation to each other. It's probably a bit small to appreciate on here but I tried to add more detail to the bear's face to contrast with the more simplistic shapes elsewhere, hopefully adding character.
