Karl Böhm conducts the Wiener Symphoniker. The Symphony in E flat major is the first work of the famous symphonic triptych (K. 543, K. 550 and K. 551) Mozart composed in the summer of 1788. Although we do not know exactly why he wrote these three masterpieces at that time, it is assumed that they were intended for a series of concerts in Vienna. Despite his waning popularity in Vienna and his desperate financial situation, Mozart succeeded in forgetting his daily concerns and created a masterpiece of good spirits and self-confidence. Austrian conductor Karl Böhm (1894-1981) was universally acclaimed for his Mozart interpretations. Though Wagner was one of Böhm's first loves, his friendship with Richard Strauss led to a deep knowledge and appreciation of Mozart. In his autobiography, Böhm wrote that "Richard Strauss revealed to me the ultimate secrets of this, in my opinion, greatest of all musical geniuses, Mozart." Böhm's discovery of these secrets transformed his Mozart interpretations into unforgettable events.
