Italian conductor Claudio Abbado leads pan-European youth orchestra Gustav Mahler Jugendorchester and soprano soloist Juliane Banse in works by two giants of 19th- and 20th-century Austrian music. Drawing on the talents of the Continent's best young musicians, the orchestra proves that musical sensitivity isn't the exclusive domain of veteran players in this performance of Arnold Schoenberg's "Pelleas and Melisande" and Mahler's Symphony no. 4.
