Last year at An Event Apart in Seattle I was giving a talk about long-term thinking on the web, using The Session as a case study. As a cheap gimmick, I played a tune on my mandolin during the talk.
Chris Coyier was also speaking. He plays mandolin too. Barry—one of the conference attendees—also plays mandolin. So we sat outside, passing my mandolin around.
Barry is back this year and he brought his mandolin with him. I showed him an Irish jig. He showed me a bluegrass tune. Together we played a reel that crossed the Atlantic ocean.
