Here is an amazing concert featuring 25 years of music from Hayao Miyazaki's world-famous Studio Ghibli's animated productions, some of which are shown on a huge screen in excerpts to accompany the music. All the music was (I believe) composed by their brilliant composer Joe Hisaishi, who also conducts the orchestra and choirs at this event in Budokan and plays the piano.
It's nearly two hours long in total, so you might wish to watch it in several sessions. I think after just the first few minutes you will want to go through the whole event, so be prepared to be captivated. There is a lot of life, fun, variety and considerable style in this collection, even though one item sounds somewhat Wagner-ish!
Items featured come from Nausicaa of the Valley of the Wind, Princess Mononoke, Spirited Away, Porco Rosso, Ponyo On The Cliff By The Sea, Kiki's Delivery Service, a few of the truly excellent pieces from Howl's Moving Castle (and not forgetting Laputa: Castle In The Sky while we're with the mobile castles) and of course My Neighbour Totoro. How could anyone forget him?
My favourite piece? Has to be the lovely waltz Merry-go-Round of Life from Howl's Moving Castle, starting at 1:18:10...
