Since I went to that Legend of Zelda: Symphony of the Goddess orchestra thing they had a few years back, I've been getting a constant stream of newsletters from Philadelphia's "The Mann" outlining new musical performances, etc etc. Typical ad stuff, but I have noticed a pretty decent selection of modern, popular soundtracks that people may be interested in, so it may be worth signing up for their newsletter and/or keeping yourself up-to-date with their calendar.
They recently announced a Pokemon Symphony, which could be interesting: http://manncenter.org/events/2014-08-20/pokemon
In the past they've done the Zelda symphony, a Star Trek Into Darkness orchestra, and a Gladiator orchestra.
Anyway, anyone in the NY/NJ/PA tri-state area may be interested in this and/or watching it in the future.
