If this first song recital of the season is any indication of the level we can expect at the Konzerthaus, lovers of Lieder are in for a real treat. Christian Gerhaher and Gerold Huber set the bar very high last night in a hefty program including Schumann’s Dichterliebe and a dozen other songs, a set of Fauré, and the world première of a song cycle by Jörg Widmann.
