 The cumulative hours, I think, that these kids have spent on their instruments is, you know, you can't even count them. But you hear the result. I mean, they sound pretty fantastic, don't they? Boy, yes. This program is extra special this year because I was able to bring in ten musicians from the Chicago Symphony to mentor the kids and work with them on this Mahler Symphony. And then we're taking the entire orchestra to the Ravinia Festival.
