Richard Strauss spent nearly a decade and a half writing Eine Alpensinfonie, a work describing the impressions of a mountain hike with such clarity that the score could almost be considered film music sans film. Don Juan's premiere (1889) established the reputation of the 24-year-old Strauss as the most important composer since Richard Wagner. Francois -Xavier Roth, one of the most charismatic and enterprising conductors of his generation, took on the role of Principal Conductor of the SWR Sinfonieorchester Baden-Baden und Freiburg in September 2011.
