I heard about Steam Powered Giraffe for the first time when Hank Green tweeted a link to the Honeybee music video in February 2012. I saw/met them for the first time at their last Balboa Park show in March 2012.
That summer, during which I took a lot of photos of them at the zoo, they approached me to do their next studio shoot, which we did in September 2012. James and I have been working with them ever since!
So next month will be our 2 year anniversary of working together. :)
