Joe Hisaishi is taking his orchestral performances of his Studio Ghibli scores on tour through Europe. Here's a terrific video of his recent appearance in Paris. It's interesting to see him on tour, and it would be nice to imagine a visit to the US. The odds of that happening are pretty slim, however. Studio Ghibli very much remains an unknown entity to most of the country.
Dedicated Hisaishi fans will want to pick up his concert DVD/Blu-Ray, which is available in Japan on the Ghibli ga Ippai label. I'm sure your money is being saved up for the feature films, but it's nice to know there's always another addition to your library.
