My DS has asked me to find out if there are any places to see bands or ochestras play during out trip (week after Thanksgiving). He plays the trumpet! The only one I know of is at the Candelight Processional. Are there any other places? Maybe Downtown? 

Other than that, the only place that I can think of off-hand is the Mariachi Band at the Mexico Pavillion at Epcot. I talked to a trumpet player there. Unfortunately, I can list a number of bands that USED to perform, but don't anymore-Future Corps, Main Street Marching Band, Future World Brass, Tomorrowland Countdown. But Tomorrowland Countdown isn't officially gone, ask at MK CIty Hall-they're very good if you can see them. If DS is college aged, he might consider trying out for the Disney All American Band that plays in the summer. Check
