As for the Kansas City Symphony, my fiancee and I went to the Friday night showing which did not have the technical difficulties mentioned for the Thursday night concert. It was an amazing experience! I liked the usage of light (red for war/kazadum etc. and green for the shire, and i think blue for Lothlorien). The video-screens were nice because they showed concept art and paintings by John Howe and Alan Lee! I much prefer this to showing movie-footage! The choir's did an amazing job! And I was blown away by the performance of "Gollum's Song"!
