Pianist Eschenbach, baritone Goerne plunge into churning stream of Schubert’s ‘Müllerin’

Preview: Baritone Matthias Goerne and pianist Christoph Eschenbach have collaborated many times on Schubert’s famous song-cycles – including the tragic “Schöne Müllerin,” which they will perform Jan. 19 at Orchestra Hall. It is an ever-evolving dramatic adventure, says Eschenbach, literally a flowing river which these two actors, baritone and pianist, can never experience twice in the same way.
