The Mann Center recently played shorts from Disney's Fantasia and Fantasia 2000, with the Philadelphia Orchestra playing live in front of the main screen. They didn't perform Rhapsody in Blue (my favorite), but it was still glorious.
The conductor and the musicians were phenomenal. To not look at the screen but still hit every single mark...I mean, I know they're professionals, but holy crap, they did a great job. The entire show was perfect from start to finish, and if it wasn't, I sure didn't notice. I really hope this becomes an annual thing. I would see it every time--you know, as long as they changed up the song list here and there.
