A couple of years ago I was at a gathering of writers and climate change activists at a retreat center above the Columbia River Gorge. I was participating in the discussion and playing music for the get together. Also participating was a young writer from Montana named Hank Green. Hank runs the blog Ecogeek.org which reviews green technology, and, with his brother John, the website Vlogbrothers.
Some weeks after the workshop Hank sent me a 58 second animated video illustrating a poem he'd written, and asked if I'd be interested in providing music for it. Over the course of a week I messed around with several different styles and instruments, and sent him 2 or 3 drafts to choose from. Here's the way it turned out:
Hank clearly had nurtured his fan base: within a week or so of posting the video, it had some 40,000 hits. Now, a couple years later, it has twice that.
The resulting fame has been fabulous.
