Quite possibly the best concert I have seen. From start to finish it was novel, participatory and utterly enthralling.
Here are some standout moments:
Demonstration of the universal power of the pentatonic scale
Ave Maria with audience participation
A condensed version of the Wizard of Oz
The audience participation was absolutely stellar, from a choir of the entire audience to a smaller choir on stage to modern dance with improvised music.
He invited the Canadian a cappella group Cadence up to sing a number on their own, and to do one with them. To be honest, they weren't as good as another British a cappella group I know, but it was fun to see Bobby interacting with other musicians.
A great show, I would definitely see him again and again.
