A new training orchestra, tuition free, and with a fellowship for three years is starting in fall of 2015. It will reward an MM to the participants (but it doesn't matter if one has postgraduate degrees already.) It will have curatorial components, as well and a required Capstone project. http://www.longy.edu/academics/graduate-degrees-and-programs/programs/training-orchestra/training-orchestra-degree-program/
It is run by Longy and Bard College.
It looks to me like an exciting option either after undergrad or post grad studies, or in the early stages of a professional career.
