Mission and Program Overview
Mission
The marinus ensemble is a chamber music collective that draws on the best emerging international performers to celebrate the human power of our great chamber music repertoire. At the heart of marinus is a commitment to enliven the audience experience through a distinctive concert approach, giving performances that are both searching and authentic. Our musicians have great training (curtis, julliard, new england conservatory) and are based out of great organizations (the metropolitan opera, national symphony, pittsburgh symphony, a far cry, konservatorium bern, the vega string quartet). Most importantly, they have a shared vision of making great music come alive for diverse audiences.
